Hello, did anyone ever notice problems with wrong/changed SNMP ifIndex settings after ISSU? We ISSU upgraded a MX from 10.4R9.2 to 11.4R7.5 and after this some of the ifIndex changed. When doing the ISSU it brought down FPC-1 (which is a MPC Type 2). Maybe thats why the ifIndex were changed. (We are running mixed DPCE and MPC) Anyway now i do have the problem that some of the interfaces do no longer have a snmp ifIndex at all:
user@router> show interfaces ge-1/0/2.1
Logical interface ge-1/0/2.1 (Index 333) (SNMP ifIndex 0)
Description: C28711
Flags: SNMP-Traps VLAN-Tag [ 0x8100.141 ] Encapsulation: ENET2
Input packets : 6785935
Output packets: 4257005
Protocol inet, MTU: 1500
Flags: No-Redirects, Sendbcast-pkt-to-re
[...]
(this is a interface on the MPC card)
I saw some posts about this happening on EX but none on MX.
How do i get the ifIndex right? The workaround for EX doesnt help as
there is no such process to restart on MX series.
Best regards,
Jonas
