Updating Switches and Ports via SNMP

Switch and switchport details can be updated automatically via SNMP using a cronjob such as:

10 * * * * /path/to/ixp-manager/bin/ixptool.php -a switch-cli.snmp-poll

This will echo any changes to stdout. If there are no changes and no errors then no information is printed. Possible options include:

• -v - verbose output
• -p switch=$name where $name is the switch name as defined in the switch table. Without this parameter, all active switches are polled.
• -p noflush=1 performs a dry run with no details saved to the database.

NB: If using multiple -p options, separate them with a comma such as: -p switch=$name,noflush=1.

Switch Details

Details such as operating system and version are gathered.

The information gathered by this is visible on the Switch page (select Switches on the left menu) and then click the OS View button on the top right.

SwitchPort Details

This same script will also poll all switch ports and:

• update details such as ifAlias, operational and admin states, speed, etc;
• alert on new ports found;
• alert of ports that have disappeared.

These details can be seen on the Operation View of the SwitchPort controller (select Switches and then Switch Ports on the left).
