Dear,
   I Have on Enterasys B5G124624 switch, (FW: 06.71.03.0025, HW : BCM56514 REV 1, Bp : 02.02.51), when I enable routing inter vlan, using command ip routing, the switch accept command,, but I don't see it in configuration ( output of command show conf) and also there's no routing between my vlan.
   I have a same problem in other switch.
  Could you help me with this issue?
   Thank you.
best regards
Hamid
