NOTE: WordPress is distorting my images so until I figure out why, all the screen shots in this post are meduim/thumbnail size and can be viewed in full size when clicked on. In this post I was running 12.2(58) on one of the 2960 switches in my lab C2960TT-L I believe, I was able to place a client one vlan and ping across to another two VLAN attached to the 2960 with no other routing device in the path. Something else I found pretty interesting is the fact my other VLAN interface disappeared from the routing table (172.16.1.0 /24 which is in the previous screen capture, which is a connected route!) So this feature really is limited but it is there none the less. I placed 22 routes into configuration mode and after #16 the switch silently discarded the rest of the routes. So I put this to the test and added over 20+ static routes: Now, there you have it routing on a Catalyst 2960 the important thing is to remember the limit of 16 static routes. The Catalyst 2960 now has the option for ‘lanbase-routing’, which is the SDM we need to enable.Ĭheck it out!! A routing table on a Catalyst 2960!

(IE: Mac tables, routing tables, unicast/multicast, QoS, etc -Obviously not all of those pertain to the 2960).

If you are not familiar with the SDM templates on Catalyst switches they are definitely worth a look at it, especially since the SDM template instructs the switch how to curve up resources to the TCAM. Now in regards to the configuration, once you have 12.2(55) or newer loaded on your 2960 you will need to make sure the switch is running the proper SDM (No, not Security Device Manager for those that are unfortunate to remember it) Switching Database Manager.
Remember one of those static routes can be a default route up to a distribution switches’ HSRP address (or VSS Core) allowing you to implement a routed access layer for cheap! Now don’t go expecting to run OSPF or EIGRP on a 2960, in fact it does not support any routing protocol, so your natural reaction is going to be then what is the point? Well it supports inter-vlan routing and up 16 static routes.
The show capabilities shows that the interface can use 802.1q, but when I try to CLI the command the work encapsulation is not an option. I have a Cisco 2960 switch that is not allowing me to setup switchport trunk encapsulation dot1q on a trunking interface. This feature was introduced in IOS 12.2(55) and requires LAN Base which has been around since late last year, however it is not a very known feature which shocks me! I figured the addition of routing (Albeit limited routing functionality) on a 2960 switch would have been some great news! 2960 will not allow 'switchport trunk encapsulation dot1q' CLI. You can now route on the low-end layer 2 Catalyst 2960 switches (Sounds like one bad oxymoron right?).
