Limiting Port Admission Bandwidth

mroute port admission-bandwidth-limit
164
and the OIF count on the port count exceeds that limit, no OIFs on that port are added
to mroutes (that is, new OIFs are blocked).
Use to configure a limit on the number of mroute OIFs that can be added across different
virtual routers, on a port.
Example
host1(config)#mroute port 3/0 limit 10
Use the no version to remove any OIF port limits.
See mroute port limit.
Port-level multicast admission control is performed when an OIF on that port is added
to the mroute for a given (S,G) multicast data stream and the multicast bandwidth map
contains a set admission-bandwidth action for that (S,G).
When enabled, the admission-bandwidth for a particular (S,G) is read from the multicast
bandwidth map and recorded in the mroute when the (S,G) mroute is created. When an
IOF is subsequently added to the mroute, the OIF is blocked from forwarding data if the
additional bandwidth contributed by the (S,G) would exceed the admission-bandwidth
limit for the port on which the interface resides.
CAUTION: Before you can limit port-level admission bandwidth, you must first create
a bandwidth map. See "Defining a Multicast Bandwidth Map" on page 148 for details.

Enabling Port Admission Bandwidth Control

You can use the mroute port admission-bandwidth-limit command to limit the total
multicast bandwidth that can be admitted on a port. The admitted bandwidth is summed
across all virtual routers with IPv4 and IPv6 mroutes that have OIFs on the port.
NOTE: Admission bandwidth values for a given (S,G) mroute are determined from the
bandwidth map. See "Defining a Multicast Bandwidth Map" on page 148 for details.
Use to configure a limit on the admission bandwidth of OIFs containing IPv4 or IPv6
mroutes, across different virtual routers, on a port.
Example
host1(config)#mroute port admission-bandwidth-limit 3000000
Use the no version to remove any OIF admission bandwidth limits.
See mroute port admission-bandwidth-limit.
