Commands for Device E
Since the configuration in Figure 11.17 on page 11-45 is symmetrical, the commands for configuring device E are
identical to the commands for configuring device A.
FastIron SuperX RouterE(config)# vlan 101 by port
FastIron SuperX RouterE(config-vlan-101)# tagged ethernet 2/1
FastIron SuperX RouterE(config-vlan-101)# untagged ethernet 1/1
FastIron SuperX RouterE(config-vlan-101)# exit
FastIron SuperX RouterE(config)# vlan 102 by port
FastIron SuperX RouterE(config-vlan-102)# tagged ethernet 2/1
FastIron SuperX RouterE(config-vlan-102)# untagged ethernet 1/2
FastIron SuperX RouterE(config-vlan-102)# exit
FastIron SuperX RouterE(config)# vlan 103 by port
FastIron SuperX RouterE(config-vlan-103)# tagged ethernet 2/1
FastIron SuperX RouterE(config-vlan-103)# untagged ethernet 1/3
FastIron SuperX RouterE(config-vlan-103)# exit
FastIron SuperX RouterE(config)# vlan 104 by port
FastIron SuperX RouterE(config-vlan-104)# tagged ethernet 2/1
FastIron SuperX RouterE(config-vlan-104)# untagged ethernet 1/4
FastIron SuperX RouterE(config-vlan-104)# exit
FastIron SuperX RouterE(config)# vlan 105 by port
FastIron SuperX RouterE(config-vlan-105)# tagged ethernet 2/1
FastIron SuperX RouterE(config-vlan-105)# untagged ethernet 1/5
FastIron SuperX RouterE(config-vlan-105)# exit
FastIron SuperX RouterE(config)# write memory
Commands for Device F
The commands for configuring device F are identical to the commands for configuring device E. In this example,
since the port numbers on each side of the configuration in Figure 11.17 on page 11-45 are symmetrical, the
configuration of device F is also identical to the configuration of device A and device B.
FastIron SuperX RouterF(config)# vlan 101 by port
FastIron SuperX RouterF(config-vlan-101)# tagged ethernet 2/1
FastIron SuperX RouterF(config-vlan-101)# untagged ethernet 1/1
FastIron SuperX RouterF(config-vlan-101)# exit
FastIron SuperX RouterF(config)# vlan 102 by port
FastIron SuperX RouterF(config-vlan-102)# tagged ethernet 2/1
FastIron SuperX RouterF(config-vlan-102)# untagged ethernet 1/2
FastIron SuperX RouterF(config-vlan-102)# exit
FastIron SuperX RouterF(config)# vlan 103 by port
FastIron SuperX RouterF(config-vlan-103)# tagged ethernet 2/1
FastIron SuperX RouterF(config-vlan-103)# untagged ethernet 1/3
FastIron SuperX RouterF(config-vlan-103)# exit
FastIron SuperX RouterF(config)# vlan 104 by port
FastIron SuperX RouterF(config-vlan-104)# tagged ethernet 2/1
FastIron SuperX RouterF(config-vlan-104)# untagged ethernet 1/4
FastIron SuperX RouterF(config-vlan-104)# exit
FastIron SuperX RouterF(config)# vlan 105 by port
FastIron SuperX RouterF(config-vlan-105)# tagged ethernet 2/1
FastIron SuperX RouterF(config-vlan-105)# untagged ethernet 1/5
FastIron SuperX RouterF(config-vlan-105)# exit
FastIron SuperX RouterF(config)# write memory
Configuring 802.1Q-in-Q Tagging
802.1Q tagging is an IEEE standard that enables a networking device to add information to a Layer 2 packet in
order to identify the VLAN membership of the packet. Foundry devices tag a packet by adding a four-byte tag to
