Configures multicast streams for acceleration. Multicasting allows group transmission of data streams.

Supported in the following platforms:

  • Access Points — AP505i, AP510i/e, AP560i/h
  • Service Platforms — NX5500, NX7500, NX9500, NX9600, VX9000

client-timeout <5-6000>>

Configures a timeout period in seconds for wireless clients

  • <5-6000> – Specify a value from 5 - 6000 seconds. The default is 60 seconds.

max-client-streams <1-4>

Configures the maximum number of accelerated multicast streams per client

  • <1-4> – Specify a value from 1 - 4. The default is 2.

max-streams <0-256>

Configures the maximum number of accelerated multicast streams per radio

  • <0-256> – Specify a value from 0 - 256. The default is 25.

overflow-policy [reject|revert]

Specifies the policy in case too many clients register simultaneously. The radio QoS policy can be configured to follow one of the following courses of action:

  • reject – Rejects new clients. The default overflow policy is reject.

  • revert – Reverts to regular multicast delivery

When the number of wireless clients using accelerated multicast exceeds the configured value (max-streams), the radio can either reject new wireless clients or revert existing clients to a non-accelerated state.

stream-threshold <1-500>

Configures the number of multicast packets per second threshold value. Once this threshold is crossed, the system triggers streams to accelerate.

  • <1-500> – Specify a value from 1 - 500. The default is 25 packets per second.
