Sup720 6506 ios updating on and weeeeeeeeeeeeeeeeeeeeeeeeeeeek
Cisco Switching/Routing :: Trunking With 4948 And 6506Apr 23, 2012
We purchased two new 4948 with two 10GE uplink ports and upgraded the devices to run IOS 15. My 6506 is running Sup 720 with s77233-adventerprisek0_wan-mz.122-33.SXI9. Currently we have 4948's connected to the same 6506's with no problems. Today I tried to add the new switches with new IOS and it caused of of my 6506 core switches to failover. I can't explain why because it was close to start of business and couldn't do much troubleshooting.
Currently we have four 4948 (running IOS 12.2(14) switches running Layer2 connecting dually to each of the two 6506 cores via 10GE fiber uplinks. I tried to add two more to the scenario, again running layer2 and dual-honing them to each of te 6506 switches. there are two 6506 core switches and they run HSRP and spanning tree is manually set to give priority to even vlans on one 6506 and odds on the other 6506. Also the new switches I tried to add did had rootguard applied as well as the uplinks.
We have to get this working and have no test environment to work with. We need to do this late this evening after close of business.
On another note, I have had problems upgrading some of my older 4948's to IOS 15. I followed Cisco's suggestion and upgraded the EPROM first and then the IOS upgrade took on three of the switches that were ordered rather recently. The four that were ordered in one batch will not take the upgrade even following Cisco's instruction and lots of other tricks. Nothing works. Having problems with IOS 15, in general?

Cisco Switching/Routing :: 3750 - L2 Trunking Versus L3 SwitchingDec 9, 2011
some of our switches have the switchport mode trunk command configured between the 3750 switches but other 3750 switches connected to our 6509 core switch do not have the switchport mode trunk command to permit Vlans from going across the swtiches instead it has an ip address and says no switchport what is the difference between does two. Is trunking used only for Layer 2 and L3 is used to route interface vlans?View 2 RepliesView Related
Cisco Switching/Routing :: VTP Trunking On 2801Feb 20, 2012
I am very new at this, but we have a 2801 router running 12.4, a 3560 that acts as the "Core" switch, and a bunch of remote 2960G's that connect via fiber to different buildings.
I am tasked to VLAN this network to reduce broadcast traffic. I started by setting up a VLAN 169 on the "3560" named the VTP domain, changed to version 2, and no password. THe Core switch and remote switch can share the VTP info, I HAD the Router seeing it too (able to ping 192.168.169.1) until I changed the "Domain" and "VTP Version"
The switches see each other fine, my problem is the Router sub interface 0/0.169 I cannot get to see the VTP domain. I imagine because I don't have a "Trunk port" set on the Router, but the option is not there. Meaning I cannot do a "switchport mode trunk" on it. The only thing I see is to make it:
TCRouter(config-subif)#encapsulation dot1Q 169 native
But, my "int fas 0/0" is used now as the main interface for our "only" network 192.168.0.0, do I need to turn this over to a subinterface and make it "Native" then the difference of the subinterfaces will advertise? Here is some of my conf:
TCCoreSW#sh vtp status
VTP Version : running VTP2
Configuration Revision: 8
Maximum VLANs supported locally : 1005

Cisco Switching/Routing :: 3750 Stack And TrunkingMar 5, 2012
I currently have 5 3750s connected via Stackwise. This stack is connected back to my core (6509s) via fiber (1Gig to Core1 & 1Gig to Core2). I want to move the 5th 3750 to another closet due to an addition of a new patch panel. Due to max length of 10 ft. for stackwise, my plan is to connect this 5th switch back to the stack using trunked fiber ports, with them being an etherchannel (2Gig). Also plan to use single fiber port form 2 different switches in the stack to provide some redundancy for the 5th switch. Should I be alert of any issues with this connection design? Do I need to properly remove the 5th switch from the stack using, no sw 5 provison sw-model or can I just disconnect stackwise and connect back with fiber?View 2 RepliesView Related
Cisco Switching/Routing :: 4506 / 6506 - Multicast RoutingMar 8, 2013
I am configuring multicast in a environment where I have a 4506 at each site (4 total) and a 6506 as the core. Each 4506 is connected via layer 3 to the 6506. I have a mix of 3560s, 3548s, and 2960s connected to the 4506s and the 6506 via layer 2 trunk
I have multiple multicast sources and hosts communicating at a time (multiple cameras sending video / multiple computers receiving video). So this is not a scenario where there is 1 sender and many receivers. This would be many senders (~50) and some receivers (~10)
6506 --> 4506 --> 3548
| --> 2960
4506 --> 2960
I configured ip multicast-routing on each of the 4506s and on the 6506. IGMP snooping is on by default on the 3560 and 2960 switches. CGMP is on by default on the 3548 switches.
I set up PIM sparse-dense mode and IGMP version 3 on each of the layer 3 interfaces for the 4506s and 6506 where they connect and on each VLAN that is sending or receiving multicast. Multicast is working throughout the network, however I am looking to verify the configuration as I scale this out to more clients on the network.
#1 - Is it correct to us sparse-dense mode in this configuration?
#2 - Do I need to configure a rendezvous points using AUTO-RP? (ip pim send-rp-announce INTERFACE scope TTL). Not sure here if I need to designate this and what to choose. Right now I do not have this and it is working, but documentation seems to infer that I need to designate this.
#3 - Is there any other configuration settings I should be considering? I hard to find real world configurations of multicast as examples or people that know multicast routing well.
Cisco Switching/Routing :: Bootvar With New IOS Name On 6506Dec 20, 2012
I upgraded the IOS on 6506E, SUP 720-10GE, non-redundant, to a new one, rebooted OK. Switch seems to work fine but "show bootvar" shows the previous IOS name instead of the new one: s72033-advipservicesk9_wan-mz.122-33.SXJ3.bin.Removed the old IOS name on "boot var", gave it new IOS name, "show bootvar" now has correct new IOS name, write mem again and reloaded switch.It booted up OK but "show bootvar" still has the old IOS: "s72033-ipbasek9-mz.122-33.SXI2a.bin".According to IOS upgrade procedure, after all the upgrade IOS steps done, then just "write mem" then the "bootvar: will have the new IOS name, but on my switch it is always has the old IOS name ? How can I set the bootvar to new IOS name?View 4 RepliesView Related
Cisco Switching/Routing :: Cat 6506 Goes Into ROMmonNov 29, 2012
I have a Cat6506. There were 2 Sup 720 in it for redundancy. They told me they had problems with this thing in the past needing to go out and reboot the machine. I need to go out periodically because it goes into ROMMON. I type boot and it comes back up. One time though neither one would reboot. I had to take a third one out there and reconfigure it. Now it is starting to do the same thing. One thing I did notice is they never connected it to an UPS. It is plugged strait into the wall with power going to two outlets. I am beginning to think there are spikes in the power occurring and this is sending it into ROMMON.View 6 RepliesView Related

Cisco Switching/Routing :: 6506 - How To Apply ACLDec 7, 2011
Access-group only allows me to set the mode.access-group > mode > prefer > port > int g2/1,Those are the only options available to me, it doesn't allow me to go.ip access-group <name> in or out or access-group <name> in or out.
I realize the commands may be a little off, I don't have a switch nearby. When I get on our 3750 there are no issues, it allows you to apply the ACL the conventional way. I just can't seem to find any way to apply an ACL on an interface on the 6506 though.
Cisco Switching/Routing :: Configuring 4507R For LACP And Trunking?Apr 3, 2008
We're trying to configure our Cisco 4507 (Supervisor Engine IV) to allow a new Dell server with a pair of Broadcom 5708 GigE NIC's to aggregate its NIC's to give us a 2gbps link to the switch.
So far we seem to have got the team and LACP up and enabled, but the adaptor that the Broadcom Admin Util creates for the team is only showing a 1gbps connection where I would have expected it to show as 2gbps.
The individual NICs show as connected at 1gbps. We're not Cisco experts so are struggling on how to get the 2 NICs to aggregate.
On the server side we've done nothing other than create a team using 802.3ad LINk Aggregation using LACP.
This is what I think the relevent output from "sho conf" is, more available if needed.

Cisco Switching/Routing :: C2900 / Trunking Between Router And 2 Distribution?Oct 20, 2012
Imagine I am designing a small network with a C2900 router running OSPF and in the future BGP with service provider. Please see attached diagram.The router is connected to (2) C3750 Layer 3 distribution switches. Then one C3560 layer 2 switch to serve future IP phone users and desktops.
a)If I connect the router interface to the (2) 3750 switches, if I make the router interface fa0/0 and fa0/1 as a trunk to accomodate VLAN 200 and other future VLANs, don't I have a problem with overlapping networks between router interface fa0/0 and fa0/1?
b)Alternatively, I could make the Router1 fa0/0 and fa0/1 configured with IP addresses and advertised in OSPF. Then the SW1 fa0/24 and and SW2 fa0/24 I could make as 'no switchport and create a routed interface port' with IP addresses, also running OSPF. Question is, from a scalable design perspectie, would you create 2 management networks and use those when assigning the IP addresses for Router1 fa0/1 and fa0/2? Because again Router1 fa0/1 and fa0/2 obviously need to be placed on different networks to avoid overlapping. So my question is more about proper network planning design to make this scalable to accomodate future VLANs in the future.Using trunks between the Router1 and SW1 option:

Cisco Switching/Routing :: 3560 CG Port Goes Down When Configuring TrunkingJan 31, 2012
I have a 3560 8 port switch. Int gi0/9 is trunked to another switch downstream. When I try to configure int gi0/10 to trunk to a switch upstream the interface on the switch goes down and I have to either reboot the switch or plug directly into the switch and telnet into it to turn off trunking on the interface. When I configure trunking on the interface on the upstream switch that connects to this interface the same happens on that switch. The upstream switch is a 3750 with 12 sfp ports. Several interfaces are trunking to other switches from this switch. Spanning tree is not configured on the 3750 at all , and is not configured on either gi0/10 or gi0/9 on the 3560. I was consoled into the 3560 during a reboot after the interface went down, a message came up that said something like "Spanning Tree returning gigabit ethernet 10 to constant state" Why would I get this message if spanning tree is not enabled on the gig ports on either end of the trunk? There is no loop to require spanning tree to shut down an interface. I have several other 3560's configured as I would like to configure this switch and they are trunking without issue.View 8 RepliesView Related
Cisco Switching/Routing :: Trunking Between Catalyst 2950 Switches?May 14, 2012
have setup a small lab as per CBTNuggets. Everything was going well until I introduced a second switch to create a trunk. Now I cannot ping between my two switches. Both show operational mode as down:
SWITCH1#show interfaces f0/12 switchport
Administrative Mode: trunk
Operational Mode: down
Administrative Trunking Encapsulation: dot1q
I have tried to allow all vlans or vlan 1 specifically and the output of the above doesn't seem to change. I am wondering if there is something in the config-register that is preventing trunking, but I don't really know enough yet!
The output of my second switch is identical to this one, the only difference is that I have it configured as a vtp client.

Cisco Switching/Routing :: Trunking With HWIC-4ESW On 1921?Feb 27, 2012
We have been facing a problem at my company ! We have a Cisco Router 1921 with one HWIC-4ESW in trunking with a RuggedCom switch RSG2100.When I use the GigabitEthernet port to make a trunk, I create 2 sub-interfaces (one for each Vlan) and configure the Port on Switch as Trunk, the inter-VLan routing works with no problem.But now I need to use this configuration using the HWIC-4ESW on Router, and I can't do this work. I try creat interface Vlan for each vlan, and try creating the VLans at Router Vlans database, but no way. At router I enter in interface and try to do the switchport trunk command to add a Vlan, but doesn't work.View 4 RepliesView Related
Cisco Switching/Routing :: 2960 / QoS Tagging And Dot1q Trunking?Nov 9, 2011
If you have a router with multiple direct vanilla FE (non trunked) interfaces on a switch trying to send QOS tagged packets to a wifi bridge several switches away does the trunking in the switched infrastructure mess with the qos tags if no qos is configured on the switches.
Does it depend on the switch? We have new 2960's running 12.2 and a few older 2950's running 12.1

Cisco Switching/Routing :: DHCP Snooping On 6506Mar 2, 2013
I have a problem with high CPU load by DHCP Snooping process on Catalyst 6506 (WS-SUP720-3B, soft: s72033-ipservices_wan-mz.122-18.SXF11.bin). I have it enabled on 15 VLANS, in which there are subscriber devices residing, and sending DHCP requests through Cisco to DHCP server (Cisco acts as DHCP relay, and it's collecting the snooping database, I also use DAI).
Snooping database contains 6962 bindings now.
CPU load goes high only sometimes, and I don't have a clue, why it's going so high. It can load as high as 45-47% of CPU, like this:
PID Runtime(ms) Invoked uSecs 5Sec 1Min 5Min TTY Process
116 81471244 322596368 252 42.95% 43.48% 36.06% 0 DHCP Snooping
When the load is high, the command: show ip dhcp snooping statistics is showing, that the overall quantity of
Packets Processed by DHCP Snooping is increasing rapidly. In normal situations, it's like 10-20 packets per second, but when the load is high, it's 1000-10000 pps.
But when I look at SPAN from my subscriber's VLANS, I don't really see any flood of DHCP requests, or something like that - everything looks as usual. Maybe, some of subscriber's devices are sending incorrect DHCP requests, that are causing packets to loop inside RP, or something like that? How can I detect that thing?
Also I thought, that if I enable the ip dhcp snooping trust mode on all of the Catalyst interfaces, the DHCP snooping will not process the subscribers DHCP packets, and I can, by exclusion of interfaces from one to one, detect, from which interface the problem is originating. But this seems to be incorrect, I turned the ip dhcsp snooping trust on all interfaces, and I still get spikes of CPU load by DHCP snooping process. Why it's still examining packets, even on trusted interfaces, is it ok?
And one more question - if I disable the ip dhcp snooping globally, will it clear all my existing bindings in snooping database?
