Packet loss between Cisco ME3400 and Juniper MX960 trunk link.
[ Edited ]
Hello , guys , as the tittle says:
Im having some problems with the configuration posted bellow:
Im able to ping :
From 172.22.0.254 (mx960) to 172.22.0.253 (me3400) on vlan2 and
From 172.23.0.254 (mx960) to 172.23.0.253 (me3400) on vlan3
Without any packet loss.
then , from:
From 172.22.0.254 (mx960) to 172.22.0.1, host on vlan2 and
From 172.23.0.254 (mx960) to 172.23.0.1, host on vlan3
I have an %22 packet loss average.
I think it could be related to a mismatch encapsulation issue.
btw , my 3400 does not support the "switchport trunk encapsulation dot1q" directive.
Ok , here is the scenario:
Also there are some messages at me3400 console:
.May 28 10:03:39.917: %SW_MATM-4-MACFLAP_NOTIF: Host 7819.f7bd.e7f0 in vlan 2 is flapping between port Gi0/8 and port Po2 .May 28 10:03:55.092: %SW_MATM-4-MACFLAP_NOTIF: Host 7819.f7bd.e7f0 in vlan 2 is flapping between port Gi0/9 and port Po2
After reading a while , Im thinking about a layer2 loop. but .... How is that possible ?
Between my MX960 and the Me3400 is only one possible path.
7819.f7bd.e7f0 is the irb mac at MX960 ... so could the loop be on the interfaces within the link agregation?
