TROUBLESHOOTING MANAGEMENT CONNECTIONS

PORT BYPASS CONDITIONS AND RECOVERY

Problem Recommended Action

Serial cable installed

but connection does

not appear on terminal

1. Cycle power by reinstalling the power cord.

2. Check the terminal emulation program’s serial port parameters.

3. Replace the serial cable. (Make sure it is a null modem cable.)

Ethernet cable

installed but Web

Manager does not

appear

1. Ensure that a crossover ethernet cable is used (unless using an

ethernet hub).

2. Check the IP addresses on the switch and workstation as follows:

At a command line prompt, type ping

DNSorIP

(where DNSorIP is the

switch’s DNS name or IP address) and press ENTER.

If a “Reply from…” or “...is alive...” message appears, the devices can

communicate.

If a “Request timed out” message appears (or the command times out),

the devices cannot communicate. Trace the cabling. If needed,

reconnect the devices.

Operational Condition Recovery

Rx_los is asserted by

an SFP/GBIC

The port stays bypassed until rx_los is de-asserted. At that time, the port

insertion will be automatically retried. The port continues to stay bypassed

until the port can pass the port insertion criteria.

Tx_fault is asserted by

an SFP/GBIC

The port stays bypassed until tx_fault is de-asserted. At that time, the port

insertion will be automatically retried. The port continues to stay bypassed

until the port can pass the port insertion criteria.

F8 Failure notification

is received by the port

(when the LIP F8

Recover policy is

enabled)

The switch automatically tries to re-insert the device, by sending F7

Initialization notifications to the device connected to the bypassed port.

The port continues to stay bypassed until the device returns F7

Initialization notifications to the port and passes the port insertion criteria.

Loss of Sync (>100ms) The port stays bypassed until a signal is re-established. At that time, the

port insertion will be automatically retried. The port continues to stay

bypassed until the port can pass the port insertion criteria.

Firmware Initiated The port stays bypassed until the firmware sets the port control back to

automatic. At that time, the port insertion will be automatically retried. The

port continues to stay bypassed until the port can pass the port insertion

criteria.
