I have Cisco router Model Cisco 3825 IOS 12.4(3b) System Bootstrap, Version 12.3(11r) T2, RELEASE SOFTWARE (fc1).
ifDescr (SNMP oid in mib2) of one of VLAN sub interface is
âGigabitEthernet0/0.445.1Q vLAN subifâ
Now I have upgraded its IOS to IOS 12.4(9t).
ifDescr of same interface is now âGigabitEthernet0/0.445â
Due to this change my monitoring tool is not discovery this interface.
In all previous IOS versions ifDescr of VLAN sub interface contains âvLANâ string. So I want to know why this change in ifDescr done by Cisco. Will all next IOS versions will follow this change.
Or is there any way to change ifDescr of interface.
