How to use the debug function of DLSw
It is very helpful for the user to have some knowledge of DLSW before
configuring DLSW. Data Link
Switching(DLSw)is a new type of tunneling
or encapsulaton protocol and it can encapsulate the frame of Logical Link
Control Type1(LL1)or Type2(LL2)coming from SNA and NetBIOS
system and enables the frame to get across non-SNA framework network. The
formulation of DLSw offers the solution to the limitation that LLC2 is not able
to transmit on the wide area network (WAN) as the design of LLC2 is based on the
local area network (LAN). DLSw also offers a solution to the transition from SNA
network to TCP/IP network, enabling SNA and TCP/IP to co-exist.
DLSw is jointly made by multiple network developers and is designed for
replacing the original various tunneling protocols. The development of DLSW
module is based on the fact that the current banking system universally employs
IBM mainframe and private SNA network framework system. DLSW module will follow
the international standards of DLSW and implements the communication with DLSw+
of CISCO router.
Based on the implementation of DLSw of this version, the configuration command offered by the module can be used for the debug of DLSw, including the local configuration of DLSw, the remote configuration of DLSw, the configuration of reachable and unreachable resources of DLSw, configuring the static MAC address and bridge group communicable to DLSw, which have important impacts on the test of DLSw made by the user.
The command below can be used under global configuration mode:
Command |
Purpose
|
dlsw
local-peer [peer-id ip-address]
[cost cost] [lf
size] [keepalive seconds]
[init-pacing-window size]
[max-pacing-window size]
[promiscuous] |
The command is used for
configuring local peer of DLSW to designate local IP address connected
with TCP. The “NO” format of the command can be used for anceling
the configuration. |
dlsw
remote-peer
list-number ip-address
[backup-peer ip-address [backup-static | linger
minutes | circuit-inactivity minutes]] | [circuit-weight
weight] | [cost cost] | [dynamic [inactivity
minutes | no-llc minutes]] | [keepalive seconds]
| [lf size] | [passive] | [priority [priority-vendor-id
id-number]] | [tcp-queue-max size] |
The command is used for
configuring the remote peer to set up TCP channel. A router can be
configured with multiple remote peers. The “NO” format of the
command can used for canceling the configuration. |
dlsw
port-list list-number type number |
The command is used for
configuring the list based on the port. Through the application of
list-number to the command “dlsw remote-peer”, the function of
filtrating dlsw packet can be implemented. The “NO” format of the
command can be used for canceling the configuration. |
dlsw
bgroup-list list-number bgroups number |
The command is used for
configuring the list based on bridge-group. Through the application of
list-number to the command “dlsw remote-peer”, the function of
filtrating dlsw can be implemented. The “NO” format of the command
can be used for canceling the configuration. |
dlsw
timer {sna-cache-timeout
| explorer-wait-time} time |
The command is used for
configuring some clock used by dlsw. The clocks that can be implemented
and configured are: cache-timeout clock and clock waiting for the
response of remote dlsw to explorer packets. The “NO” format of the
command can be used for canceling the configuration. |
dlsw load-balance [round-robin |
circuit-count circuit weight] |
The command is used for
configuring the implementation of local or remote load-balance function
on the local DLSw The “NO” format of the command can be used for
canceling the configuration. |
dlsw icanreach {mac-exclusive |
mac-address mac-addr | saps} |
The command is used for
configuring the destination reachable to local DLSw. The “NO” format
of the command can be used for canceling the configuration. |
dlsw icannotreach saps sap
[sap...] |
The command is used for
designating SAP unreachable to the local. The “NO” format of the
command can be used for canceling the setting. |
dlsw mac-addr mac-addr |
The command is used for
configuring the static MAC address. The “NO” format of the command
is used for canceling the setting. The command is related to the local
buffer and remote buffer. |
dlsw bridge-group group-number [sap-priority
list-number] |
The command is used for
configuring bridge group communicable to DLSw. The “NO” format of
the command can be used for canceling the setting. |
dlsw udp-disable |
The command is used for closing
down UDP send method of DLSw. The “NO” format of the command can be
used for canceling the setting. |
sap-priority-list
list-number
[high|medium|normal|low]
[dmac mac-address] [smac
mac-address] [dsap sap-value]
[ssap sap-value] |
The command is used for
configuring the preference queue based on MAC/SAP. The “NO” format
of the command can be used for canceling the setting. |
How
to use the displaying ability of DLSw
The command below can be used under management status and global configuration mode:
Command |
Purpose |
show dlsw capabilities [
ip-address ip-address | local] |
Through displaying the information of exchange
of capabilities, the user can have a better understanding of the various
situations of occurring in the process of exchange of capabilities of DLSw.
|
show dlsw circuits [detail]
[mac-address address |
sap-value value | circuit id] |
Through displaying the virtual
circuit of DLSw, the user can learn the status information of all the
circuits. |
show dlsw peers [ip-address ip-address ] |
Through the command, the various information of remote DLSw can be displayed. |
show dlsw reachability [[local | remote] | [mac-address address] |
Through the command, the buffer information of DLSw can be displayed, including local buffer and remote buffer. |
How
to use the debug function of DLSw
When DLSw function is used on the router, the debug function of DLSw can be used for monitoring the running of DLSw.
The commnand below can be used under management status:
Command |
Purpose |
debug dlsw error |
The command is used for
exporting the erroneous debug information. |
debug dlsw state [tcp ip-address
| circuit circuit-id | explorer mac-address] |
The command is used for
exporting the debug information of internal state machine of DLSw |
debug dlsw event [detail] |
The command is used for
exporting the debug information of internal state machine of DLSw |
debug dlsw flow-control |
The command is used for
exporting the debug information of flow control processing. |
debug dlsw packet |
The command is used for
exporting the debug information of internal state machine of DLSw |
How to
use the management function of DLSw
When DLSw function is used on the router, the management function of DLSw can be used for clearing the circuit of DLSw and statistic information.
The command below can be used under management status:
Command |
Purpose |
clear dlsw circuit [circuit-id] |
The command is
used for clearing the circuit of DLSw |
clear dlsw reachability |
The command is used for clearing the statistic information of DLSw. |
