Brocade Virtual ADX Installation and Deployment Guide (Supporting ADX v03.1.00) - Manual (Page 55)

Displaying interface information
Use the following steps and commands to display interface information.
1. Logon to your Brocade Virtual ADX.
2. To display information about the interfaces available on a device use the following command.
Virtual ADX# show interface brief
Port Link State Dupl Speed Trunk Tag Priori MAC Name
1 Up Forward Full 10G None No level0 000c.2973.098c
2 Up Forward Full 10G None No level0 000c.2973.0996
3 Up Forward Full 10G None No level0 000c.2973.09a0
4 Up Forward Full 10G None No level0 000c.2973.09aa
5 Up Forward Full 10G None No level0 000c.2973.09b4
6 Up Forward Full 10G None No level0 000c.2973.09be
7 Up Forward Full 10G None No level0 000c.2973.09c8
8 Up Forward Full 10G None No level0 000c.2973.09d2
mgmt1 Up Forward Full 10G None No level0 000c.2973.0982
To display information about a specific interface, enter a command such as the following:
Virtual ADX# show interface 6

TCP checksum offload
TCP checksum offload improves performance by offloading hardware checksum calculation to the
network adapter.
This functionality is disabled by default as not all network adapters support the checksum calculation.
Once you have determined that your network adapter supports the checksum calculation, you can
enable the functionality on the Brocade Virtual ADX to further optimize performance.
NOTE
For details of where checksum calculation is performed, when virtual and physical NICs have different
TCP checksum offload settings, refer to the hypervisor documentation.
