The following example adds an entry that tags all frames from IP address 192.168.10.1
destined for IP address 192.168.20.1 with a VLAN ID of 100, and a L2CoS value of 3.
switch:admin> portcfg vlantag 8/ge0 add 192.168.10.1 100 3 192.168.20.1
The following example adds an entry that tags al frames from a crossport with local address
192.168.11.20, VLAN ID of 200, and a LSCoS value of 1.
switch:admin> portcfg vlantag 8/xge0 add 192.168.11.20 200 1 –x
3. Display display the VLAN tag configuration use the portshow vlantag command as follows:
switch:admin> portshow vlantag 8/ge0
switch:admin> portshow vlantag 8/xge0
For more details on using the portCfg vlantag and portshow vlantag commands refer to the Fabric
OS Command Reference Manual.
Compression options
The following compression options are available on both the 7800 switch and the FX8-24 blade.
Compression is defined on the FCIP tunnel.
• Standard - This is a hardware compression mode.
• Moderate - This is a combination of hardware and software compression that provides more
compression than hardware compression alone. This option supports up to 8 Gbps of FC
traffic.
• Aggressive - This is software-only compression that provides a more aggressive algorithm than
used for the standard and moderate options. This option supports up to 2.5 Gbps of FC traffic.
• Auto - This allows the system to set the best compression mode based on the tunnel’s
configured bandwidth and the aggregate bandwidth of all tunnels in the 7800 switch or FX8-24
blade.
NOTE
Fibre Channel throughput for all compression modes depends on the compression ratio achievable
for the data pattern. Brocade makes no promises, guarantees, or assumptions about compression
ratio that any application may achieve.
Follow the guidelines for assigning explicit compression levels for tunnels in Table 6.
TABLE 6 Assigning compression levels
Total effective tunnels FC side bandwidth Compression level
Equal to or Less than 512 Mbps Aggressive
More than 512 and less than or equal to 2 Gbps Moderate
More than 2 Gbps Standard
