Brocade recommends using the Association ACL screen strategically to name and configure
ACL policies meeting the requirements of the particular WLANs they may map to. However, be
careful not to name ACLs after specific WLANs, as individual ACL policies can be used by more
than one WLAN.
•
You cannot apply more than one MAC based ACL to a Layer 2 interface. If a MAC ACL is already
configured on a Layer 2 interface, and a new MAC ACL is applied to the interface, the new ACL
replaces the previously configured one.
SMART RF
Self Monitoring At Run Time RF Management (SMART RF) is a Brocade innovation designed to
simplify RF configurations for new deployments, while (over time) providing on-going deployment
optimization radio performance improvements.
Smart RF can reduce deployment costs by scanning the RF environment to determine the best
channel and transmit power configuration for each managed radio.
Smart RF centralizes the decision process and makes intelligent RF configuration decisions using
information obtained from the RF environment. Smart RF helps reduce ongoing management and
maintenance costs through periodic re-calibration of the network. Re-calibration can be initiated
manually or can be automatically scheduled to ensure the RF configuration is optimized to factor
for RF environment changes (such as new sources of interference, or neighboring access points).
NOTE
Unlike a controller or service platform, an access point utilizes a single Smart RF configuration it can
use with other access points of the same model. However, the Smart RF policy needs to be activated
from any one of the Smart RF screens. Numerous Smart RF policies cannot be defined on behalf of
the access point.
Smart RF also provides self-healing functions by monitoring the network in real-time and provides
automatic mitigation from potentially problematic events such as radio interference, coverage
holes and radio failures. Smart RF employs self-healing to enable a WLAN to better maintain
wireless client performance and site coverage during dynamic RF environment changes, which
typically require manual reconfiguration to resolve.
Brocade recommends you keep in mind that if a Smart RF managed radio is operating in WLAN
mode on a channel requiring DFS, it will switch channels if radar is detected.
•
If Smart RF is enabled, the radio picks a channel defined in the Smart RF policy.
•
If Smart RF is disabled, but a Smart RF policy is mapped, the radio picks a channels
specified in the Smart RF policy
•
If no SMART RF policy is mapped, the radio selects a random channel
If the radio is a dedicated sensor, it stops termination on that channel if a neighboring access point
detects radar. The access point attempts to come back to its original channel (statically configured
or selected by Smart RF) after the channel evacuation period has expired.
Change this behavior using a
no dfs-rehome
command from the CLI. This keeps the radio on the
newly selected channel and prevents the radio from coming back to the original channel, even after
the channel evacuation period.
