Catalyst 6500 Series Switch Command Reference—Release 8.6

Chapter 2 Catalyst 6500 Series Switch and ROM Monitor Commands
set errordetection
The rapid boot feature minimizes the amount of downtime a module experiences if the module
encounters a packet-buffer error. You can enter one of the following commands to handle the error
condition:
• set errordetection packet-buffer errdisable—If you enter the errdisable keyword, only ports that
experience the packet-buffer error are put in errdisable state.
• set errordetection packet-buffer powercycle—If you enter the powercycle keyword, the module
is power cycled. When you choose this option, a ROMMON image is downloaded on the module,
and the normal bootup sequence is bypassed to reduce module downtime.
• supervisor—If you enter the supervisor errdisable keywords, the supervisor engine ports that
experience the packet-buffer errors are put in the errdisable state. If you enter the supervisor
shutdown keywords, the supervisor engine ports that experience the packet-buffer errors are shut
down.
Caution Do not power cycle the module when the ROMMON image is downloading. Doing so might damage
the module.
The rapid boot feature is available on the following modules:
• WS-X6248-RJ45
• WS-X6248-TELCO
• WS-X6348-RJ45
• WS-X6348-RJ21
• WS-X6148-RJ45
• WS-X6148-RJ21
The set errordetection link-errors global commands allow you to configure link error handling. When
entering the set errordetection link-errors commands, follow these guidelines:
• set errordetection link-errors action {errordisable | port-failover}
If the error count for a port reaches the high value for the configurable threshold (within the
sampling count period specified), the action is either errordisable or port-failover. If you select
errordisable, the port goes into the errdisable state when the high threshold is reached. If you select
port-failover, the channel status of the port is considered. The port goes into the errdisable state if
the port is in a channel and is not the last operational port in the channel. The port also goes into
errdisable state if it is a single port.
• set errordetection link-errors interval value
The interval value that you specify determines how often the error counter for a port is read.
• set errordetection link-errors threshold {inerrors | rxcrc | txcrc} [high value] [low value]
The threshold values that you specify determine how many link errors are allowed during the
interval that you specify by entering the set errordetection interval value command. If the low
threshold is reached (within the sampling count period specified), a syslog message is displayed. If
the high threshold is reached (within the sampling count period specified), in addition to displaying
a syslog message, the port is either errdisabled or the port failover mechanism takes effect.
When you enter the inerrors keyword, the ifInErrors counter is checked. For packet-oriented
interfaces, the ifInErrors counter includes the number of inbound packets that contained errors
preventing them from being deliverable to a higher-layer protocol. For character-oriented or
fixed-length interfaces, the ifInErrors counter includes the number of inbound transmission units
that contained errors that prevented them from being delivered to a higher-layer protocol.
