In enhanced switching mode, each port can be configured for
switching or routing mode. This usage differs from the routing and
switching modes, in which all ports must be in either switching or
routing mode. The uPIM in enhanced switching mode provides the following
features:
Supports configuration of different types of VLANs and
inter-VLAN routing
Supports Layer 2 control plane protocols such as Spanning
Tree Protocol (STP) and Link Aggregation Control Protocol (LACP)
Supports Port-based Network Access Control (PNAC) by means
of authentication servers
Note:
You can configure uPIM in enhanced switching mode only in 9.2
Release or later.
