5400 firmware K14.47 issues

[DMcCoy_1]

Since putting 14.47 on my core 5400 my 802.1x Vista clients no longer get a dhcp ip address after changing VLAN at boot. XP clients do, although the dhcp request is much delayed on XP anyway. Once authenticated I can disable and enable the adaptor and it will get an address.

Also, connecting via ssh to edge switches is painfully slow.

Returning to K13.63 fixes both the dhcp addresses for client and the slow ssh. Configuration remains the same between versions.

Are you performing 802.1X on the core switch or on the edge? Have you got DHCP-Snooping enabled or DHCP relay enabled on the 5400 switch?

802.1x is performed by the edge switches, the relevant vlans have a forwarder set to the dhcp server.

It's all worked fine for the last year on 13.xx, just changing to 14.47 stops it working.
