620 Appendix B � Configuring the Catalyst 1900 Switch
Lab B.5: Configuring Trunking
Before we can share information with our second switch, we need to configure
the link between the switches. We don’t necessarily have to configure a
trunked link, but then only VLAN 1 information would be transferred
between switches, and we want to configure all VLANs’ information to be
transferred between switches.
1. On 1900A, configure port 26 to be in auto trunk mode. This will
allow the link to become trunked as soon as we set the second switch’s
trunk port to on.
1900A#config t
Enter configuration commands, one per line. End
with CNTL/Z
1900A(config)#int f0/26
1900A(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 auto
2. Attach to the second 1900 switch and name the switch 1900B. Create
port 26 as a permanent trunk port.
#config t
Enter configuration commands, one per line. End
with CNTL/Z
(config)#hostname 1900B
1900B(config)#int f0/26
1900B(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
1900B(config-if)#trunk on
