How to terminate Layer 2 Circuits using H-VPLS This article explains how to terminate Layer 2 Circuits using H-VPLS. On one side of the Layer 2 Circuit we have VLAN tagged interface towards CE and on the remote end side of the Layer 2 Circuit we have an untagged interface towards CE. On ACX-4000: ============= lab@ACX-4000-1# show interfaces lo0 unit 0 { family … [Read more...]
How to stop duplication of traffic to different vlans in the same VPLS instance (For ADPC cards)
VPLS traffic destined to one particular vlan under a VPLS instance, can be duplicated to all other vlans and on different interfaces, on the same vpls instance. This behaviour was found only in DPC cards. When tested on MPC cards the traffic destined for one particular vlan was not duplicated to other vlans This is an expected behaior for a BUM traffic (Broadcast, … [Read more...]
COSD_GENCFG_WRITE_FAILED
This article describes the following syslog message: COSD_GENCFG_WRITE_FAILED The class-of-service process (COSD) uses GENCFG to read/write data from the kernel. If the write fails, the kernel returns an error. The reason for the failure is given after the message, as in the following log example: COSD_GENCFG_WRITE_FAILED: GENCFG write failed for Classifier to IFL 74. … [Read more...]
