Hello

I have question related to X25 over LLC2 (XOL).

Topology,

HpServer(x25_XOL)<>(FE,CMNS--CiscoRouter—S0/0(X.25)

The X25 work fine when we use the default DSAP/SSAP 0x7E, , however DSAP/SSAP change to 0x7C or 0x7A, cisco router reject the LLC connection

We noticed the reject message in debug llc and it also show in show llc output .

The following from HP explain that DSAP value can be from range 0X70 to 0X7e, we use alternate DSAP value multiple X25 logical session on the same server.

Many thanks in advance for any input and advise on the router config.
