IOS support for DHCP snooping

[Vinayaka Raman]

I am running DHCP snooping for VLAN 1 on below switch

IOS (tm) C2950 Software (C2950-I6Q4L2-M), Version 12.1(22)EA4a, RELEASE SOFTWARE (fc1)

Model number: WS-C2950-24

Looks like below IOS does not support snooping.

Model number: WS-C2950-24

IOS (tm) C2950 Software (C2950-I6Q4L2-M), Version 12.1(14)EA1a, RELEASE SOFTWARE (fc1)

Can you please let me know which IOS support snooping feature?

There are not too many releases below 12.1(22) which I would recommend.

Especially 12.1(19) is infamous.

Therefore, my advice would be to upgrade all switches to 12.1(22).
