[j-nsp] SONET interface flapping

[Ramesh Karki]

Hi all,

I am using STM-1 OC3 interface on my M10i and its connected to Cisco other
side. The interface is up but not stable. The log messages shows frequent up
down cause also the bgp session got flaps.

Feb  7 12:37:12  mib2d[4785]: SNMP_TRAP_LINK_DOWN: ifIndex 131,
ifAdminStatus up(1), ifOperStatus down(2), ifName so-0/1/1.0
Feb  7 12:37:12  rpd[4502]: EVENT UpDown so-0/1/1.0 index 69 x.x.x.x ->
x.x.x.x <Broadcast PointToPoint Multicast Localup>
Feb  7 12:37:12  rpd[4502]: EVENT <UpDown> so-0/1/1.0 index 69 <Broadcast
PointToPoint Multicast>
Feb  7 12:37:14  mib2d[4785]: SNMP_TRAP_LINK_UP: ifIndex 131, ifAdminStatus
up(1), ifOperStatus up(1), ifName so-0/1/1.0
Feb  7 12:37:14  rpd[4502]: EVENT <UpDown> so-0/1/1.0 index 69 <Up Broadcast
PointToPoint Multicast>
Feb  7 12:37:14  rpd[4502]: EVENT <Flags> so-0/1/1.0 index 69 <Up Broadcast
PointToPoint Multicast>
Feb  7 12:37:14  rpd[4502]: EVENT UpDown so-0/1/1.0 index 69 <Up Broadcast
PointToPoint Multicast>
Feb  7 12:37:14  rpd[4502]: EVENT UpDown so-0/1/1.0 index 69 x.x.x.x ->
x.x.x.x <Up Broadcast PointToPoint Multicast>

But when I execute the command # show interfaces so-0/1/1 there is no flap
it seems to be stable.

Has anyone face the same problem ??

The software version we are using is 9.2. I have listed the configuration of
interfaces both JunOS and IOS, can someone please suggested in it.
