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 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.
