Additional information :In the ip arp list, there are no flags such as * (Adjacencies learnt on non-active FHRP router) or + (Adjacencies synced via CFSoE)Would this indicate that some additional feature is needed for either CFSoE or learning on non-...

This is useful.Do the 16 supervisor queues refer to the priority-levels ?There is still the question about setting the CoS or DSCP value in this outgoing traffic, as the following (L2) switch will base its QoS treatment on the QoS marking in the rece...
