Protocol Configuration Reference
Version 3.3 Volume 1
Use the SCSP monitoring function to monitoring the state of server
synchronization.
Use the following procedure to access the SCSP monitoring
commands. This process gives you access to the SCSP
monitoring process.
- At the OPCON prompt, enter talk 5.
(For more detail on this command, refer to "The OPCON Process and
Commands" in the Software User's Guide.) For example:
* talk 5
+
After you enter the talk 5 command, the GWCON prompt
(+) is displayed on the terminal. If the prompt does not
appear when you first enter configuration, press Return
again.
- At the + prompt, enter the protocol scsp command to get you to
the SCSP prompt.
Example:
+ prot scsp

This section describes the SCSP monitoring commands. You can
access SCSP monitoring commands at the SCSP> prompt. Table 42 shows the commands.

Use the List command to display information about the state of
server synchronization. You can also enter a ? after a specific command
name to list its options.
Syntax:
- list
- dcs . . .
-
- server-groups . . .
- dcs interface sgid
- Lists the all DCSs within a server group.
- interface
- Specifies the interface number that the DCS is defined upon.
- sgid
- Specifies the server-group identifier of this DCS.
Example:
SCSP>li dcs
Network number [0]?
Server Group ID [0]?
DCS Id HFSM State CAFSM State M/S CRL Len ReTran Len
03.04.02.00 Bidirectional Aligned S 0 0
- DCS Id
- The hex identifier of the DCS (on the other end of the VCC).
- HFSM State
- The state of the Hello Finite State Machine for this DCS session.
The states are:
- Down_Inop
- The channel to the DCS is down.
- Down
- The channel to the DCS is down, but an open is in progress.
- Waiting
- The Local Server (LS) has sent an Hello message to the DCS and it is
waiting for a response.
- Unidirectional
- The LS has received a Hello message from the DCS but it has not yet
recognized this Local Server.
- Bidirectional
- The LS and the Directly Connected Server recognize each other. This
is the normal state.
- CAFSM State
- The state of the Cache Alignment Finite State Machine for this DCS
session. The states are:
- Down
- Cache alignment has not yet begun.
- MS_Neg
- The LS and the DCS are negotiating for Master/Slave status.
- Summarize
- The LS and DCS are exchanging cache summarization information.
- Update
- The LS and DCS are exchanging full cache information.
- Aligned
- The LS and DCS are synchronized. This is the normal state.
- M/S
- Indicates Master (M) or Secondary (S) status of this LS. This is
significant only if the CAFSM is in Summarize, Update, or Aligned
state.
- CRL Len
- Cache Length Request List length. This is the number of cache
update records that remain to be sent during Update state.
- ReTran Len
- ReTransmit list length. This is the number of cache update records
that remain to be acknowledged by the DCS.
- server-groups interface
- Lists information about all server groups.
- interface
- network interface number
Example:
SCSP config> list ser

- sgid
- Server Group Identifier. This is the configured identifier for the
servers in this server group (LIS).
- Protocol
- The type of database being exchanged.
- lsid
- Hex value of the Local Server Identifier. This identifies this
Server within the server group. For ATMARP, this is the client's
IP address.
- DCSs
- The number of Directly Connected Servers associated with this Local
Server.
- ATM address
- The ATM address of this Local Server. DCSs must use this to set up
connections with this Local Server.
Use this command to show statistics for a Directly Connected
Server.
Use the Statistics command to display information about the
state of server synchronization. You can also enter a ? after a
specific command name to list its options.
Syntax:
- statistics
- interface server-group dcs-id
- interface
- Specifies the interface number that the DCS is defined upon.
Valid values: Any defined interface
Default value: 0
- server-group
- Specifies the server-group of this DCS.
Valid values: 0 - 65535
Default value: 0
- dcs-id
- Specifies the hex identifier of the DCS (on the other end of the
VCC).
Valid Values:

- Key
- The hex cache key value for this cache entry. For ATM ARP this
corresponds to the server's IP address (in hex).
