BigIron RX Series Configuration Guide 30553-1001986-01Configuring 802.1q-in-q tagging 11Commands for device FThe commands for configuring device F are identical to the commands for configuring device E. Inthis example, since the port numbers on each side of the configuration in Figure 24 on page 300are symmetrical, the configuration of device F is also identical to the configuration of device A anddevice B.BigIron RX-F(config)# vlan 101BigIron RX-F(config-vlan-101)# tagged ethernet 2/1BigIron RX-F(config-vlan-101)# untagged ethernet 1/1BigIron RX-F(config-vlan-101)# exitBigIron RX-F(config)# vlan 102BigIron RX-F(config-vlan-102)# tagged ethernet 2/1BigIron RX-F(config-vlan-102)# untagged ethernet 1/2BigIron RX-F(config-vlan-102)# exitBigIron RX-F(config)# vlan 103BigIron RX-F(config-vlan-103)# tagged ethernet 2/1BigIron RX-F(config-vlan-103)# untagged ethernet 1/3BigIron RX-F(config-vlan-103)# exitBigIron RX-F(config)# vlan 104BigIron RX-F(config-vlan-104)# tagged ethernet 2/1BigIron RX-F(config-vlan-104)# untagged ethernet 1/4BigIron RX-F(config-vlan-104)# exitBigIron RX-F(config)# vlan 105BigIron RX-F(config-vlan-105)# tagged ethernet 2/1BigIron RX-F(config-vlan-105)# untagged ethernet 1/5BigIron RX-F(config-vlan-105)# exitBigIron RX-F(config)# write memoryConfiguring 802.1q-in-q tagging802.1Q-in-Q tagging enables you to configure 802.1Q tag-types on a group of ports, such as trunkports, thereby enabling the creation of two identical 802.1Q tags (802.1Q-in-Q tagging) on a singledevice. This feature 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.Figure 25 on page 305 shows an 802.1Q configuration example.FIGURE 25 802.1Q configuration exampleTo customer interface ProviderEdge SwitchUplink to provider cloudUntagged TaggedDA SA 8100 CustomerVLAN DA SA 8100 CustomerVLANProviderVLAN9100
