I'm trying to configure a monitor-session over a pseudowire between an ASR9K and a NCS5508, both running IOS-XR 24.1.1. On the ASR, the monitor source is a 100G bundle and the destination is a l2vpn xconnect to the NCS On the NCS, the xconnect from ...

Hi, I'm growing increasingly frustrated trying to implement the simplest possible outbound QoS policy on an NCS5500 running 24.1.1. All I need is to be able to set CoS outbound on a bundle subinterface. All outbound traffic on that subinterface need...

Community, We have an ASR 9910 running 7.9.21 with a A9K-4HG-FLEX-SE card in it. We have tried a few of the different groupings that include 1G ports shown to be available in the "show controllers np valid-port-groups all loca 0/1/CPU0" command. Whil...

We're in the process of replacing a long list of Nexus C3064PQ chassis with C93180YC-FX3s. Many of those 3064s are paired together and have a crosslink configured for IPv4 and IPv6 for iBGP peering. For some reason, we cannot get IPv6 working (not ev...

Hi. I'm trying to do some static NAT on a Nexus 9K and was wondering if there's a way to have it automatically do a one-for-one translation based on subnets instead of host IPs. In other words, I'd like to translate the Outside Global subnet of 192.1...

I figured out the problem. The source port being monitored is a LACP bundle with no subinterfaces. Mirroring the full bundle and sending it across the psuedowire and out a subinterface on another bundle caused that destination bundle to get confused ...

I believe I found the problem. I saw in the documentation that setting CoS on subinterfaces that do push/swap rewrites on vlan tags is not supported. I changed up our configs to push the outer tag further downstream and just set the subinterface to e...

Any chance there's an equivalent of this page for the NCS5500 platform? Would love to see the default marking behavior for all those scenarios for those devices as well.

@anpetit , we are trying to use GLC-TE transceivers in those 1G ports. I see now that they are not listed in the compatibility matrix for the A9K-4HG-FLEX-SE cards.

Harold, Here's the output you requested. Note that in the "show ipv6 neighbor detail" output there are working IPv6 neighbors (with their IPs obscured) on another port (Po1). Also note that in the output on both routers, our Eth1/1 showed up with the...
