.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Abstraction subclass for Cisco Catalyst 3550 Layer 2/3 Switches.
.PP
These devices run \s-1IOS\s0 but have some of the same characteristics as the
Catalyst WS-C family (5xxx,6xxx).  For example, forwarding tables are held in
VLANs, and extended interface information is gleaned from \fICISCO-SWITCH-MIB\fR.
.PP
For speed or debugging purposes you can call the subclass directly, but not
after determining a more specific class using the method above.

Returns reference to hash of iid to current link duplex setting.
.Sp
Software version 12.1(22)EA1a or greater returns duplex based upon the
result of \f(CW$c3550\fR\->\fIel_duplex()\fR.  Otherwise it uses the result of
the call to \fICiscoStack::i_duplex()\fR.

Software version 12.1(22)EA1a or greater returns duplex based upon the
result of \f(CW$c3550\fR\->\fIp_duplex()\fR.  Otherwise it uses the result of
