Propagating PR #1423

The current apply_temp_view logic doesn't handle MTU configuration during warm-reboot:

Before warm-reboot:

root@sonic:/home/admin# redis-cli -n 0 HGETALL 'LAG_TABLE:PortChannel0001'
1) "admin_status"
2) "up"
3) "oper_status"
4) "up"
5) "mtu"
6) "9100"

After warm-reboot:

root@sonic:/home/admin# redis-cli -n 0 HGETALL 'LAG_TABLE:PortChannel0001'
1) "admin_status"
2) "up"
3) "oper_status"
4) "up"

This ends up in traffic disruption after ISSU end:

What I did

  • Added missing MTU filed

Why I did it

  • To fix warm-reboot apply_temp_view logic

How I verified it

  • Did warm-reboot several times with frame size equal to 9100 - no traffic disruption is observed
