I've been experiencing init (io) issue in our ubr-10k. Most of you will suggest its a config file issue but the scenario is like this.
We have 6 10k UBRs running smoothly but this 6th UBR with card c8/0/0 and c8/0/1 is having init io modems. Before our configuration is 12x6 in our combiner but we migrated the said card'ss (c8/0/0[for node1]and c8/0/1[for node2]) to 20x6, both of them. After doing so we experienced this init IO issue.
Frequency we are using before is 561000000 to 627000000 which is for 12x6 configuration since we cannot proceed with 633000000 frequency because we already used this for other cable channel purpose we then used 241000000 to 283000000 to attain the 20x6 new combining configuration.
So as mentioned above modems in the c8/0/0 and c8/0/1 card are experiencing init IO issue. This modems were before in a 12x6 configuration.
We'd like to learn a little about your network, your pain points with monitoring an enterprise network, and your preferred solution and workflow to solve issues.
