Parameter mseconds: LLC2 POLL timer length in milliseconds. The effective range is 1 to 60,000.

Description Use the llc2 timer detect command to configure the LLC2 POLL timer, namely the interval at which both ends of a virtual circuit sends/receives Receiver Ready (RR) frames after the virtual circuit is established.

Use the undo llc2 timer detect command to restore the default setting.

By default, the LLC2 POLL timer length is 30,000 milliseconds.

Example # Set the LLC2 POLL timer length to 10,000 milliseconds on Ethernet 1/0.

Parameter mseconds: LLC2 P/F waiting time in milliseconds. The effective range is 1 to 60,000.

Description Use the llc2 timer poll command to configure the LLC2 P/F waiting time, namely the amount of time the router waits for an acknowledgment after sending a P frame.

Use the undo llc2 timer poll command to restore the default setting.

By default, the LLC2 P/F waiting time is 5,000 milliseconds.

When a router sends a frame that requires an acknowledgment, the frame is sent with a poll bit set. This frame is known as a P frame. Once the router sends a P frame, it cannot send any other P frame until it receives an acknowledgment, namely a frame with a final bit set, or until the LLC2 P/F waiting time expires.

Example # Set the LLC2 P/F waiting time to 2,000 milliseconds on Ethernet 1/0.
