the mis-confniguration casued traffic on cascading DSLAM is not working

Publication Date:  2012-07-25 Views:  28 Downloads:  0
Issue Description
We have two MA5616 equipment with GE uplink. The services on the cascadin DSLAM do not work. On the uplink DSLAM, all the services work fine. All VLANs are configured on both side of the link between uplink and cascading DSLAM.
Alarm Information
Null
Handling Process
Configure the port of uplink DSLAM that connects to cascading DSLAM like this:
MA5616_1UPLINK(config-if-eth-0/0)#network-role 1 cascade
The uplink port of cascading DSLAM should be configured as uplink:
MA5616_1CASCADING(config-if-eth-0/0)#display network-role all
  ---------------------------
  PortID        Network-role
  ---------------------------
       0              uplink
       1              uplink
  ---------------------------
Root Cause
Both GE ports on the GE1A subboard of uplink DSLAM are configured as uplink ports. In this case, the traffic for the cascading DSLAM will be discarded.
MA5616_1uplink(config-if-eth-0/0)#display network-role all
  ---------------------------
  PortID        Network-role
  ---------------------------
       0              uplink
       1              uplink
  ---------------------------
