DHCP snooping on SUP2 / MSFC2

[Iulian Vaideanu]

The question is: is there such thing?  The bits and pieces of info I've found kind of contradict each other (some say it's been there since IOS SXE, some say it's not supported at all) - the fact is, we have a 6509 in our network running s222-adventerprisek9_wan-mz.122-18.SXF17a.bin on which "ip dhcp snooping" doesn't seem to be available, either in global or interface config mode...

Thank you.

Hi,

Looking at the configuration for your IOS version.

http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst6500/ios/12-2SXF/native/configuration/guide/swcg/snoodhcp.html

You need a PFC3 st support ip dhcp snooping

Configuring DHCP Snooping

---

This chapter describes how to configure Dynamic Host Configuration Protocol (DHCP) snooping on Catalyst 6500 series switches.

Note•The DHCP snooping feature requires PFC3 and Release 12.2(18)SXE and later releases. The PFC2 does not support DHCP snooping.

•For complete syntax and usage information for the commands used in this chapter, refer to the Cisco IOS Master Command List, Release 12.2SX at this URL:
