Internal Error Detection and Recovery

Version 5.3.1 contains the Internal Error Detection and Recovery

(IEDR) feature. This feature shuts down a port if its rate of internal

errors exceeds the threshold setting. Currently you can enable this

feature only by using the CLI and only for ports on 50-series and 80-

series Gigabit Ethernet modules. By default IEDR is disabled.

This feature is designed to serve as mechanism for detecting and

isolating hardware failures.

If IEDR shuts down a port, the switch will forward traffic through a

redundant port if you:

Enable a protocol that supports redundancy, such as OSPF,

VRRP, or STP, on the port

Provide an alternate path

If you do not enable a protocol that supports redundancy on the

port and provide an alternate path, you may lose traffic if the port

If you replace a module that has a port which has been disabled by

IEDR, the switch will load the startup configuration for the module

and reenable the port. However, if you save the running

configuration to the startup configuration while a port is shut down,

you will have to manually reenable the port after you replace the

module or reset the switch.

* Note: To enable IEDR for ports in a hunt group, you must use

a different command that enables the feature globally for

all ports in all hunt groups on the switch. For

information on this command, see
