Commands for configuring aggregated VLANs on device F
The commands for configuring device F are identical to the commands for configuring device E. In this
example, Because the port numbers on each side of the configuration in
Figure 88 on page 401 are
symmetrical, the configuration of device F is also identical to the configuration of device A and device
B.
deviceF(config)# vlan 101 by port
deviceF(config-vlan-101)# tagged ethernet 2/1
deviceF(config-vlan-101)# untagged ethernet 1/1
deviceF(config-vlan-101)# exit
deviceF(config)# vlan 102 by port
deviceF(config-vlan-102)# tagged ethernet 2/1
deviceF(config-vlan-102)# untagged ethernet 1/2
deviceF(config-vlan-102)# exit
deviceF(config)# vlan 103 by port
deviceF(config-vlan-103)# tagged ethernet 2/1
deviceF(config-vlan-103)# untagged ethernet 1/3
deviceF(config-vlan-103)# exit
deviceF(config)# vlan 104 by port
deviceF(config-vlan-104)# tagged ethernet 2/1
deviceF(config-vlan-104)# untagged ethernet 1/4
deviceF(config-vlan-104)# exit
deviceF(config)# vlan 105 by port
deviceF(config-vlan-105)# tagged ethernet 2/1
deviceF(config-vlan-105)# untagged ethernet 1/5
deviceF(config-vlan-105)# exit
deviceF(config)# write memory
802.1ad tagging configuration
802.1ad tagging provides finer granularity for configuring 802.1Q tagging, enabling you to configure
802.1Q tag-types on a group of ports. This feature allows you to create two identical 802.1Q tags
(802.1ad tagging) on a single device. This enhancement improves SAV interoperability between
Brocade devices and other vendors’ devices that support the 802.1Q tag-types, but are not very
flexible with the tag-types they accept.
NOTE
Brocade devices treat a double-tagged Ethernet frame as a Layer 2 only frame. The packets are not
inspected for Layer 3 and Layer 4 information, and operations are not performed on the packet
utilizing Layer 3 or Layer 4 information.
The following figure shows an example application with 802.1ad tagging.
