ATM per-VC Queuing and VC Bundling
Parameters can be applied to individual VCs either by using VC classes or by directly applying them to
the bundle members. Parameters applied to an individual VC supersede bundle-level parameters.
Parameters applied directly to a VC take precedence over the same parameters applied within a class to
the VC at the bundle-VC configuration level.
All of the QoS features are supported in per-virtual circuit (VC) and VC bundling mode. The default is
per-VC queuing mode.
VC bundling allows individual VCs going to the same destination to be grouped together. Traffic
mapping to each VC is based on traffic protocol criteria such as IP precedence. To enable VC bundling,
enter the bundle command under the ATM interface.
VC Bundling Configuration Example
The following example shows a VC bundling configuration:
vc-class atm atm-bundle
broadcast
oam-pvc manage 1
oam retry 3 3 1
encapsulation aal5snap
protocol ip inarp broadcast
oam-bundle manage 1
