SNI-PEER (SNI Peer Link)
Issue 1 May 2002
8-1493555-233-143
Notes:
For every error in Table 8-584, the SNI circuit pack reporting the error is indicating
that it has a problem with the control path, circuit path, or packet path to the SNI
peer in the slot indicated on the error table.
First, the Failure Audit test (#777) should be run to confirm whether the error still
exists.
If the SNI is reporting an SNI-PEER error against a slot that does not contain an
SNI, either change circuit pack administration via change circuit-pack to
unadminister the SNI, or insert an SNI into the indicated slot. List configuration
carrier can be used to determine whether an SNI circuit pack is inserted.
Otherwise, display errors and look at every SNI-PEER error in the log. If either
of the following two conditions are present, follow Procedure 2 below.
■ Do many SNIs have SNI-PEER errors pointing to the same 2 adjacent
SNIs?
■ Do 2 adjacent SNIs have SNI-PEER errors pointing to many other SNIs?
If neither condition is present, follow Procedure 1 below. When using either
procedure, see ‘‘SNI-BD (SNI Circuit Pack)’’ or ‘‘SNC-BD (Switch Node Clock
Circuit Pack)’’ for circuit pack replacement instructions.
Procedure 1: Proceed through the following steps until the problem is resolved:
1. Perform the Fiber Fault Isolation Procedure described in Chapter 5.
2. Replace the SNI pointed to by the SNI-PEER error type (see the SNI Slot
column in Table 8-584 on page 8-1491, ‘‘SNI-PEER Hardware Error Log
Entries’’).
3. Replace the SNI reporting the SNI-PEER error.
4. Replace the active SNC.
