2960X ip sla features

Hello everyone,

I recently replaced a couple of 2960G switches by 2960X (primarily WS-C2960X-48FPD-L). When trying to configure some ip sla operations, I noticed that the neccessary commands aren't available:

SW-048-015(config)#ip sla ?
  key-chain  Use MD5 Authentication for IP SLAs Control Messages
  responder  Enable IP SLAs Responder

What i'm used to from 2960G and 2960S models is:

SW-048-012(config)#ip sla ?
  <1-2147483647>          Entry Number
  enable                  Enable Event Notifications
  group                   Group Configuration or Group Scheduling
  key-chain               Use MD5 Authentication for IP SLAs Control Messages
  logging                 Enable Syslog
  low-memory              Configure Low Water Memory Mark
  reaction-configuration  IP SLAs Reaction-Configuration
  reaction-trigger        IP SLAs Trigger Assignment
  reset                   IP SLAs Reset
  responder               Enable IP SLAs Responder
  restart                 Restart An Active Entry
  schedule                Entry Scheduling

So does anyone have an idea, why I cannot configure ip sla operations anymore?

Additional details that might be of relevance:

SW-048-015#sh lice
Index 1 Feature: lanlite
        Period left: 0  minute  0  second
Index 2 Feature: lanbase
        Period left: Life time
        License Type: Permanent
        License State: Active, In Use
        License Priority: Medium
        License Count: Non-Counted

So I do have a LAN Base license which should theretically support ip sla (as stated in feature navigator). I have tried several IOS images without success. Currently, I'm running c2960x-universalk9-mz.150-2.EX5.bin.

Thanks in advance for any hints...



Hey,I checked and found that


I checked and found that 2960X with LAN BASE supports IP SLA responder operations only.

Thanks for your reply,well

Thanks for your reply,

well this info kind of 'helps'. Nonetheless I wonder why the feature navigator claims that several ip sla operations are supported. So I wonder where you checked?

Just for fun I just upgraded

Just for fun I just upgraded a 2960S (WS-C2960S-24PD-L) from 15.0-1.SE3 to 15.2-2.E and...

surprise: the ip sla features are gone as well. So this is obviously not an issue specific to 2960X models.

Indeed with the IOS train
