OL-5061-01

Chapter 4 Configuring the 6E3 Line Card

DSU Link Doesn’t Work

Symptom

The link between the 6E3 line card and digitial link DSU (DL3100E) doesn't work when subrates have

been configured. Pings don't go through.

Note This is an intermittent problem that occurs with the DL3100E DSU. Other supported external CSU and

DSU products are not affected.

Conditions

This symptom is observed after you have reloaded a Cisco 7304, (when a 6-port E3 line card is connected

to an external digital link DSU) and when the interface has the

dsu bandwidth command enabled.

Workaround

Enter the shutdown command followed by the no shutdown command on the affected interface.

Router#conf t

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)#int ser 5/0
