Troubleshooting Routers
5-24 117379-A Rev. A
Checking the Address Format (Bay Networks Standard Only)
If the router is running Version 7.0 or later of the Bay Networks Standard PPP, and
you defined explicit addressing, make sure the addresses are in decimal format.
(The addresses in a Series 5 router are in hexadecimal format.) If the address is
greater than 9 and in the wrong format, the synchronous link fails to activate.
Troubleshooting a Synchronous to X.21 Connection
If you connect a Bay Networks router running Series 7 or Series 8 software to a
device with an X.21 interface, do the following:
1. Set the appropriate Com port configuration jumpers on the Ethernet link
module to the X.21 setting.
See Installing and Maintaining BN Routers for instructions.
2. Enter the following command:
get wfSyncEntry.76.*
3.
Make sure that you set the synchronous polling in the router’s
synchronous line driver configuration to 2 (disabled), which is the
default.
If you set synchronous polling to 1 (enabled) and the data set ready (DSR)
lead is dropped, the software disables the synchronous driver. When you set it
to 2, the software disregards the DSR lead.
Reception Errors Incrementing or Reception Count Not Incrementing
Conduct a local loopback test of the local channel service unit (CSU) or digital
service unit (DSU). During the loopback test, check the transmission and
reception statistics.
Caution: Do not do loopback testing on a synchronous port during network
production time if the bridge is operating on that port.
