Selecting the Link Layer Protocol

Two link layer protocols, Point-to-Point Protocol (PPP) and Serial Line Internet Protocol (SLIP), are supported for connection to an external SNMP manager or network device (e.g., a router). PPP can be used for synchronous or asynchronous operation. SLIP can be used for asynchronous operation only.

The E1 NTU implementation of PPP supports the following:

•Full negotiation of PPP's Link Control Protocol (LCP).

•Active negotiation of LCP when the connection is established.

•Maximum Request Unit (MRU) sizes up to

1500 bytes, but the E1 NTU will attempt to negotiate down to 500 bytes.

•The E1 NTU provides a unique LCP magic number derived from the unit serial number and the elapsed time.

•Full negotiation of escape characters.

The E1 NTU implementation of PPP does not support Link Quality Reports (LQR), compression, encryption, Password Authentication Protocol (PAP) or Challenge Authentication Protocol (CHAP).

The E1 NTU implementation of SLIP supports a fixed MRU size of 1006 bytes.

Before selecting the protocol, you must first select the port to be used as the communications link. Refer to the Selecting the Port section on page 3-14. This example assumes that the COM port is being used as the communications link.

To select the link layer protocol,

1.From the top-level menu screen, select Cnfig.

2.Select the configuration option set to be copied into the Edit area by using the appropriate Function key. Use the scroll keys, if necessary.

3.Select Edit.

4.From the Edit screen, press the key until the SNMP selection appears on the screen.
