Title: [Wireshark-users] monitor an STM-1 link
if you are using a passive tap, you should be able to maintain bidirectional connectivity on the STM-1 and the link should have come back up. Perhaps you're tap is not passive?

Subject: [Wireshark-users] monitor an STM-1 link
Hi Experts,
we want to monitor the traffic of an STM-1 (OC-3) link
between two Cisco LS1010 ATM switches. For this purpose,
we put an optical splitter in both forward and backward
direction that produces -26 dBm signal level on the
monitored link. The receiver sensitivity on the monitor
device is stated to be -28 dBm. The receiver link on
the monitor node does not go up (after administrative shut
down is disabled).
Questions, if someone has experience:
- is it possible to force link up even no Tx I/F connected?
- does STM-1 need to have bidirectional connectivity?
thanks,
Tamas
