Chapter 4 Configuring the OC12 POS Line Card
Checking the Configuration
Beginning in Cisco IOS Release 12.(31)SB13, B3 TCA alarms will bring the line down immediately
regardless of the configured delay time when pos delay path trigger is configured; the configured trigger
delay time is not applicable to B3 TCA alarms. If pos delay path trigger is not configured, B3 TCA
alarms will not bring the line down. In releases prior to Cisco IOS Release 12.2(31)SB13, B3 TCA
alarms are not triggers for the line protocol to go down by default.
The pos delay triggers path command can also bring down the line protocol when the higher of the B2
and B3 error rates is compared with the signal failure (SF) threshold. If the SF threshold is crossed, the
line protocol of the interface goes down.
The pos delay triggers path command was introduced in Cisco IOS Release 12.0(16)S.
Checking the Configuration
After configuring the new interface, use the show commands to display the status of the new interface
or all interfaces, and use the ping command to check connectivity. This section includes the following
subsections:
• Using show Commands to Verify the New Interface Status, page 4-7
•
Using the ping Command to Verify Network Connectivity, page 4-11
Using show Commands to Verify the New Interface Status
Table 4-3 demonstrates how you can use the show commands to verify that new interfaces are configured
and operating correctly and that the OC12 POS line card appears in them correctly. Sample displays of
the output of selected show commands appear in the sections that follow. For complete command
descriptions and examples, refer to the publications listed in the
“Related Documentation” section on
page 8 .
Note The outputs that appear in this document may not match the output you receive when running these
commands. The outputs in this document are examples only.
