Adding an ESS with the CLI

—

802.11an valid rates are 6, 9, 12, 18, 24, 36, 48, and 54 Mbps, or all

— 802.11an-mcs valid rates are MCS 0, MCS 1, MCS 2, MCS 3, MCS 4, MCS 5, MCS

6, MCS 7, MCS 8, MCS 9, MCS 10, MCS 11, MCS 12, MCS 13, MCS 14, MCS 15, or all

— 802.11bgn-mcs valid rates are MCS 0, MCS 1, MCS 2, MCS 3, MCS 4, MCS 5, MCS

6, MCS 7, MCS 8, MCS 9, MCS 10, MCS 11, MCS 12, MCS 13, MCS 14, MCS 15, or all

All base rates must be entered as supported rates.

The supported data rates are the rates supported by the access points. The basic data

rates are a subset of the supported rates. The access point first tries to transmit at

the highest data rate set to Basic. If there are problems encountered in the trans-

mission, the access points steps down to the highest rate that allows data transmis-

sion.

Use the base-tx-rates command in ESSID configuration mode to configure the basic

data rates, for example, for 802.11bg:

controller(config-essid)# base-tx-rates 802.11bg

1|2|5.5|11|9|12|18|24|36|48|54|all

Use the supported-tx-rates command in ESSID configuration mode to configure the

supported transmit rates, for example, for 802.11bg:

controller(config-essid)# supported-tx-rates 802.11bg

1|2|5.5|11|9|12|18|24|36|48|54|all

To remove a base transmit rate, use the no base-tx-rates command with the mode

and speed value, for example, for 802.11bg:

controller(config-essid)# no base-tx-rates 802.11bg

1|2|5.5|11|9|12|18|24|36|48|54|all

To remove a supported transmit rate, use the no supported-tx-rates command with

the mode and speed value, for example, for 802.11bg:

controller(config-essid)# no supported-tx-rates 802.11bg

1|2|5.5|11|9|12|18|24|36|48|54|all

To display the radio data rates, use the show essid command.

Assigning a VLAN with the CLI

When creating an ESSID, you can assign a VLAN to the ESSID. This allows you isolate

an ESSID to a specific part of your network. By default, ESSIDs do not have VLANs

assigned to them. You must create a VLAN using the vlan command in global config-

uration mode before assigning the VLAN to an ESSID.

The following example assigns a vlan named corp:

controller(config-essid)# vlan corp

Note:

Changing the base rate in an ESS profile will cause all clients on all

ESSIDs to reassociate.
