I've got an issue bringing an OC48 link up between two 7750 equipped with iom2-20g + m2-oc48-sfp.
The config of each port is as follows:
Code: Select all
A:7750_A>config>port# info
----------------------------------------------
sonet-sdh
hold-time up 50
path
no shutdown
exit
exit
no shutdown
----------------------------------------------
Code: Select all
A:7750_A>config>port# show port 10/1/1

Some of you might tell me "there's a loop somewhere" but it has already been checked; none found,
software or hardware.
Thanks in advance !
