Event Code 45

# 10: 04/25/95 22:43:01 DEBUG SLOT 1 DLS Event Code: 45

SSP XID frame rcvd in LLC, conn, state, flag: 30927f70, 4, 201

This message describes the receipt of an input frame from either TCP or the DLC:

SSP XID frame rcvd in LLC -- The type of frame received (XID) and where it was

received (LLC, SDLC).

conn (30927f70) -- The unique connection identifier for this DLSw circuit. It will

correspond to the correlator described in the DLSw RFCs state (4), CIRCUIT

ESTABLISHED, as listed in the DLSw state table (refer to Table C-3

flag (201) -- Bay Networks use only.

DLSw Session Setup

Before configuring DLSw, you should be familiar with how DLSw establishes

sessions between network endpoints. To establish SNA or NetBIOS sessions

between endpoints (devices), Bay Networks routers with DLSw enabled execute

the following sequence of events:

• Upon receiving a TEST (POLL) or similar frame from an attached endstation,

the receiving slot performs the following:

-- Converts the TEST (POLL) frame into an SSP CANUREACH command.

-- Searches the appropriate cache to determine if the remote location is

known. If the remote location is already in the cache, the CANUREACH

is forwarded only to this remote location. If the remote location is not in

the cache, DLSw forwards the CANUREACH to all remote routers

specified in the DLSw Peer IP Table, if this table exists.

-- Forwards the packet to all other slots defined in the DLSw Slot Table.

• Upon receiving a CANUREACH frame, a DLSw slot:

-- Forwards the frame to all other slots defined in this router’s DLSw Slot

Table.

-- Converts the CANUREACH frame back to a TEST (POLL) frame.

-- Forwards the TEST (POLL) frame to all interfaces on this slot which have

DLSw enabled.
