If the box continues to receive excessive HDLC errors the router will continue to send bundle
down link SNMP traps. The current default threshold is 1000 HLDC errors in a row. The
threshold is now tunable and can range from 100 to 12,000. The hdlc_error command under
the system command subtree sets the threshold for all links on the router. The syntax of the
command is:
host/configure> system hdlc_error ?
NAME
hdlc_error - Setting the threshold for hdlc errors
(default: 1000)
SYNTAX
hdlc_error [ error_limit ]
DESCRIPTION
error_limit -- Number of continous hldc errors on a
link (default: 1000)
Valid Range(s) : 100 - 12000
After the excessive HLDC error threshold is exceeded there are two methods to stop the errors
on the link. The first method is to shutdown the bundle. The shutdown and no shutdown
commands are changed to deactivate or activate all the links in the bundle. Deactivating the
link stops the router from receiving any errors on that link.
The second method is to configure the router to deactivate the link when it has exceeded the
excessive HDLC error threshold. If it is a multilink bundle, the non-errored link can still pass
traffic and the customer is still up. The new command for configuring whether to deactivate
links after excessive HLDC errors is hdlc_link_deactivate under the system subtree.
The default value is to not deactivate the link when it has reached the excessive HDLC error
threshold.
When you save the configuration on the router with the command save local the HDLC
error threshold and whether to automatically deactivate the link is saved. It is then read in on
subsequent reboots.
The show system configuration command is updated to show the current settings for
both the hdlc_error and hdlc_link_deactivate command. The output is displayed
below for an Secure Router 1000 Series router:
