When there are problems with ATM-SGRP (ATM signaling group), also
investigate:
■
‘‘ATM-DCH (ATM D-Channel Port)’’
■
‘‘ATM-BCH (ATM B-Channel Trunk)’’
■
‘‘SYS-LINK (System Links)’’
■
‘‘PKT-BUS (Packet Bus)’’
Error Log Entries and Test to Clear Values
Notes:
a. Error Type 1: switch sent a message to the far-end switch or terminal
adapter, and the far-end did not respond in the allotted time. Possible
causes include link failure and congestion or outage at the far-end. The
Aux Data field contains Layer 3 protocol information used by internal
counters.
If no other symptoms are present, no action is required. If Layer 3
communication is down:
1. Check for alarms and errors against link components
2. Check out other errors against ATM-SGRP, ATM-TRK, and other
hardware components on the link.
