We have Cisco2621XM router, where in the below IP SLA is not supporting. Refering the Cisco feature navigator, understood that the below features will support c2600-ik9s-mz.122-46a.bin. But i am not able to execute IP SLA command in config mode.
The below are the features captured from Cisco feature navigator and the same are not supporting in c2600-ik9s-mz.122-46a.bin IOS.
IP SLAs - DHCP Operation
IP SLAs - Distribution of Statistics
IP SLAs - DLSW+ Operation
IP SLAs - DNS Operation
IP SLAs - FTP Operation
IP SLAs - History Statistics
IP SLAs - HTTP Operation
IP SLAs - ICMP Echo Operation
IP SLAs - ICMP Path Echo Operation
IP SLAs - One Way Measurement
IP SLAs - Reaction Threshold
IP SLAs - Scheduler
IP SLAs - SNA LU2 Echo
IP SLAs - SNMP Support
IP SLAs - TCP Connect Operation
IP SLAs - UDP Echo Operation
IP SLAs - UDP Jitter Operation
I've chosen the same features for IP SLA with Features Navigator and the lowest IOS version that support what you need it's 12.3, Enterprise features set.
I have here a 2600 with c2600-i-mz.123-1.bin, and:
<1-2147483647> Entry Number
key-chain Use MD5 authentication for RTR control message
low-memory Configure low water memory mark
reaction-configuration RTR Reaction Configuration
reaction-trigger RTR trigger assignment
reset RTR Reset
responder Enable RTR Responder
restart Restart an active entry
schedule RTR Entry Scheduling
slm Service Level Management
I think you have to upgrade.
