Configuring VLANs Using SNMP

3.2.1.2 Creating a VLAN
In addition to the checks stated in the section titled Modifying a VLAN, the
following checks are also completed, if you created a VLAN:
• If a restriction is in effect for any port selected for this VLAN. If one of these
ports is restricted from becoming a member of this VLAN, the command is
aborted.
• If the IP address was specified, the IP address is set.
• After passing all tests, the local variables are stored in the VLAN table. The
ports selected are added to the existing port list.
• If the unit is not in 802.1Q mode, the changes are saved in non-volatile
memory and used when the unit is configured in 802.1Q mode and then
rebooted.
After the hardware is informed about a VLAN in 802.1Q mode, the following
will be performed by the firmware:
- The hardware is informed of which ports on the VLAN to delete.
- The BPDU addresses and Management Processor (MP) MAC address
are added to the database, if they were not there already.
- All of the learned addresses are deleted for this VLAN.
3.2.1.3 Deleting a VLAN
In addition to the checks stated in the section titled Modifying a VLAN, the
following checks are also completed, if you deleted a VLAN:
• If any of the selected ports has this VLAN ID set for the default VLAN ID,
the command is aborted.
• If this check passes, the local variables are moved to the table entry selected
by the index variable.
• If the IP address was specified, the IP address is set.
• If the switch is operating in 802.1Q mode, the following will be performed by
the firmware:
- The hardware is informed of which ports on the VLAN to delete.
- All learned addresses for this VLAN are deleted.
