Table C-8. TCP Troubleshooting

Problem Possible Cause Action/Solution

DLSw/TCP connections do

not come up.

Improper DLS Slot Table

configuration; no IP address

configured on slot

Each slot running DLSw

requires a unique IP

address assigned to each

DLSw slot.

DLSw/TCP connections

partially come up.

No peer configured

Peer is not reachable

Add a peer and its IP

address to the Peer Table.

Check to see if IP routing

is enabled and the peer is

configured or known to

DLSw.

TCP connections come up,

but traffic is not passed.

DLSw Slot Table

configuration does not

match DLC interface

location

Correct the configuration by

creating a DLS slot entry for

every slot that has a DLC

interface.

TCP has excessive

retransmissions.

TCP window is too large

TCP is filling WAN buffers

and causing dropped

frames

Edit the TCP Window Size

parameter and specify a

smaller value.

Configure protocol

prioritization and allocate

adequate queue depth.

TCP sessions do not come

down when the IP path is

lost.

TCP Keepalive Time

parameter set to 0

Edit the Keepalive Time

parameter and specify a

value in the range 0 to

2147483647 seconds. Refer

to the Keepalive Time

parameter on page A-21 for

more information.
