I try to use the same cable connect to another 2501,
everything turns up. LMI-TYPE are cisco.
and keepalive are 10s on both side before I disable it.
I also did some debug fr lmi, it shows DTE LMI time out.
and I did switched the cable.
Now, without the keepalive, Is this considered good connection?
Thank you!
