Jun 27, 2004Im trying to determine the serial number of Gbics already installed and running on a Catalyst 2950 switch. Is there a specific command to do so? There is a command on Catalyst 4506 that gives all info regarding the Gbic ("show idprom interface gi 1/1") Is there something equivalent for 2950?

Oct 4, 2005I used to be able to set an uplink port with the interface command "port network" so that it would not learn all the mac addresses that are being flooded down to the switch. It does not seem to be there on the 2950's or 35XX switches.
Where did it go and what is replacing it? Interface is a Trunk port as well.

Cisco :: Moving PVST To RSTP / LAN Environment?
Jan 23, 2013Currently I'm with a pure Cisco shop, running every LAN Switched infrastructure (even in the HQ datacenter) with PVST+, I'm noticing in the documentation I've read and labs I've created that RSTP is... great, and I've observed that even the uplinkfast functionality seems to be build in by just enabling rapid-pvst. Of course I'll propose a migration plan, document the network, diagram it entirely and provide effective steps to implement the change, but that's assumed from any get'go.
View 1 Replies View RelatedCisco :: RSTP Configuration - 14 Switches Interconnected In Ring?
Apr 2, 2013I need to setup a layer 2 network consisting of 14 switches interconnected in a ring. Obviously, the design of 14 switches in a ring network is dumb, not here to debate that. Unfortunately, it HAS to be a ring. I've been researching the best way to configure RSTP for this. From everything I've read all I really need to do is configure Primary/Secondary root bridge in the center, and change the Maximum Age field to at least 16 seconds? From what I've read you want a minimum of 3 second buffer + 1 second for each hop due to message age being added by each switch hop?

Cisco Switching/Routing :: 7609 Slow RSTP Convergence
Nov 22, 2011I have a 7609 with two LAG groups (Etherchannel not LACP) going to two separate devices that DO NOT participate in spanning-tree (Occam gear if you must know). I'm running 802.1w across the LAG groups but the convergence time is terrible! In essence, the 7609 is running spanning tree against itself (between the two blades). What can I do to fix my configuration?
If I disable the ports on the equipment connected to g1/17 & g1/18, it takes ~30 seconds for spanning tree to start forwarding on g2/17 & g2/18.When I bring the ports back up on the other side of g1/17 & g1/18 which are in a lag group, g2/17 & g2/18 immediately go into block mode while g1/17 & g1/18 start learning for another ~30 seconds!!

Dec 26, 2011What's wrong with my config? If I shutdown a port or pull a link it takes ~30 seconds to converge.
I have set spanning-tree portfast default on the 4948's. Is it proper to set my uplinks on these switches (g1/1) to shared or does that disable RSTP?
Switch 1 & 2 are 4948's running 12.2(54)
Switch 1 & 2 are connected on port 43
Switch 1 port 1 is connected to the 7609 12.2(33) SRD5 on port g1/2 Switch 2 port 1 is connected to the 7609 on port g2/2
I have a host on Switch 1 port 42 for testing.

Oct 6, 2011Telco provided a BGP connection on MPLS network. When I connect router directly to Telco switch I can see BGP neighbor, so my router BGP config is OK. However, I need to put this router in a diffferent building and want to bring the connection over on a "trunk"; now I loose the BGP neighbor. I'm sure I did this before and it worked OK. I'm trunking between 2 x2950 switches using this config on each switch. [code]
I also configured the trunk as vlan 1214, which is the encapsulation provided by the Telco (dot1Q 1214).
