Configuring Trunk Ports
The 1900 switch only runs the Dynamic Inter-Switch Link (DISL) encapsula-
tion method. To configure trunking on a Fast Ethernet port, use the interface
command trunk parameter.
The following switch output shows the trunk configuration on interface
26 to trunk on.
1900EN#config t
Enter configuration commands, one per line. End with CNTL/Z
1900EN(config)#int f0/26
1900EN(config-if)#trunk ?
auto Set DISL state to AUTO
desirable Set DISL state to DESIRABLE
nonegotiate Set DISL state to NONEGOTIATE
off Set DISL state to OFF
on Set DISL state to ON
1900EN(config-if)#trunk on
The following list describes the different options available when setting a
trunk interface:
Auto The interface will become trunked only if the connected device is
set to on or desirable.
Desirable If a connected device is on, desirable, or auto, it will negotiate
to become a trunk port.
Nonegotiate The interface becomes a permanent ISL trunk port and will
not negotiate with any attached device.
Off The interface is disabled from running trunking and tries to convert
any attached device to be non-trunk as well.
