• Optimizing Dual 5G Mode in AP for Serial Backhaul Support on Cisco Catalyst IW9167E Heavy Duty Series Access Point

This feature enhances the performance and efficiency of a wireless network by optimizing the use of dual 5G radios in an AP for backhaul. In this feature, AP operates in the dual 5G mode using two 5G radios. You can enable backhaul on two 5G radios. The two backhaul radios provide uplink and downlink access to maximize throughput over multiple mesh hops.

Note

1. For the dual 5G serial backhaul, ensure that slot 2 operates in 5G mode when enabling mesh dual 5G serial backhaul.
2. When slot 2 operates in 6 GHz, AP is unable to be configured in mesh mode.
   The backhaul root AP (RAP) does not support multiple downlink channels. When you configure mesh mode in AP, block the 6G band for slot 2 as it does not support both backhaul and access.
   By default, the following actions are performed without any configuration change except enabling dual-5G:
3. Mesh access point (MAP) seeks for a primary device on all enabled radios.
4. MAP performs uplink and downlink on the same slot while other slots are in access mode.

• Power Profile Support with 30-watts Power over Ethernet (PoE) on Cisco Catalyst IW9167I Heavy Duty Access Point

The AP power policy allows you to define the power budget utilization available for an AP, wherein, you can define a set of policies for different interfaces on an AP.
From this release, Cisco Catalyst IW9167I Heavy Duty AP supports Power policy AP feature especially when AP works with 802.3at power.
PoE+ is a new interface introduced in Cisco Catalyst IW9167I Heavy Duty AP, in addition to the Ethernet and LAN interfaces. AP is now powered by 30W through either 802.3at or 802.3bt standards, offering versatility in deployment and ensuring high-performance wireless connectivity.
To enable flexible power policy, a power profile must be configured on the controller, extending the AP Join profile. The power profile supports local and FlexConnect modes but is unsupported in mesh mode.

• Proto Encoding: Enhancements for Emulated On-Change Subscription

For more information, see Programmability Configuration Guide.

• Quality of Service (QoS) Classification and Marking Support on WGB

WGB allows you to classify different packets from two wired ports and mark them to a different access control driver queue based on your configuration.
In addition to TCP or UDP, WGB also supports configuring the ACL rules and QoS policies based on Ethernet type, transport layer port numbers or port range, and DSCP.
During classification, the device performs a lookup and assigns a QoS label to the packet. The QoS label indicates all QoS actions to perform on the packet and identifies the queue from which the packet is sent.
The feature is supported on the following APs:

1. Cisco Catalyst IW9167E Heavy Duty Access Point
2. Cisco Catalyst IW9165E Rugged Access Point
   For more information, see the Support for QoS ACL Classification and Marking sections of the Cisco Catalyst IW9165E Rugged Access Point and Wireless Client Configuration Guide and Cisco Catalyst IW9167E Heavy Duty Access Point Configuration Guide.
