The value 40 is in the first set of 7 hex pairs, indicating that these ports are in Stack Unit 1. The hex value 40 is 0100 0000 in binary. As

described, the left-most position in the string represents Port 1. The next position from the left represents Port 2 and has a value of 1,

indicating that Port 1/2 is in VLAN 10. The remaining positions are 0, so those ports are not in the VLAN.

NOTE: The table contains none of the other information the command provides, such as port speed or whether the

ports are tagged or untagged.

Add Tagged and Untagged Ports to a VLAN

The value dot1qVlanStaticEgressPorts object is an array of all VLAN members.

The dot1qVlanStaticUntaggedPorts object is an array of only untagged VLAN members. All VLAN members that are not in

dot1qVlanStaticUntaggedPorts are tagged.

• To add a tagged port to a VLAN, write the port to the dot1qVlanStaticEgressPorts object.

• To add an untagged port to a VLAN, write the port to the dot1qVlanStaticEgressPorts and dot1qVlanStaticUntaggedPorts objects.

NOTE: Whether adding a tagged or untagged port, specify values for both dot1qVlanStaticEgressPorts and

dot1qVlanStaticUntaggedPorts.

Example of Adding an Untagged Port to a VLAN using SNMP

In the following example, Port 0/2 is added as an untagged member of VLAN 10.

Managing Overload on Startup

If you are running IS-IS, you can set a specific amount of time to prevent ingress traffic from being received after a reload and allow the

routing protocol upgrade process to complete.

To prevent ingress traffic on a router while the IS reload is implemented, use the following command.

• Set the amount of time after an IS-IS reload is performed before ingress traffic is allowed at startup.
