5300xl Switch Support for the Wireless Edge Services xl Module

Configuring 5300xl VLANs for Radio Port Adoption

The set up and configuration of VLANs used for communication between a

radio port and the downlink port of the Wireless Edge Services xl Module is

an essential element in providing wireless services in a network. This connec-

tivity enables radio port adoption, the foundation for supplying wireless

services. The 5300xl switch software (Version E.10.30 or later) has been

modified to automate much of this VLAN set up and configuration. If infra-

structure switches are used to connect radio ports to a wireless services-

enabled switch, some manual VLAN configuration is required. You also may

choose to do VLAN set up and configuration manually on the 5300xl as well.

On a 5300xl switch, two methods for automating radio port VLAN set up and

configuration are available: LLDP auto-provisioning (enabled by default) and

802.1X RADIUS-assigned VLANs (disabled by default). LLDP auto-provision-

ing and 802.1X RADIUS-assigned VLANs both temporarily override a port's

static configuration, untagged VLAN membership while the radio port connec-

tion is active. A port’s static configuration changes are saved in the switch’s

configuration, but they are not applied to the port until override control is

relinquished.

Both of these methods can be used simultaneously in a 5300xl switch. The

following switch authentication applications take precedence over LLDP:

8021.X, Web Authentication, and MAC Authentication. This means that if LLDP

is currently overriding a port's static configuration, and 802.1X authentication

is enabled on the port, LLDP's override can be superseded by an 802.1X

override. All three of the above authentication schemes take precedence over

LLDP. The show vlan <vid> CLI command list the ports being temporarily

overridden for a given VLAN, along with the application that is forcing the

override.

Note When using Layer 3 adoption, any VLAN which has the IP address of a Module

may be used. The Module’s uplink port (<slot-id>UP) or the Module’s down-

link port (<slot-id>DP), but not both, must be a member of this VLAN.

Automatic RP VLAN Operation Using LLDP

Beginning in software version E.10.30, new LLDP commands have been added

to the 5300xl software that automatically create a VLAN (the Auto-VLAN) and

assign Module and switch port VLAN memberships to establish radio port

communication with the wireless services-enabled switch. These commands
