Displaying real server information and statistics
B
Ms The master port state. This field applies only to track ports and to ports
to which you have bound other TCP/UDP ports in many-to-one
configurations.
•
For track ports, the state of the master port. When a port is
configured to track a master port, the Brocade Virtual ADX sends a
client’s request for the tracking port to the same real server as the
master port. Refer to
“Track port group function” on page 44. The
example show real server output shown above assumes that port
500 is tracked by port 600. If port 500’s state changes, port 600’s
state also changes to match.
•
For many-to-one TCP/UDP port binding, the state of the port that is
translated in the port binding between the real server and the
virtual server. The ports that are not translated follow the state of
the port that is translated. Refer to
“Multiple port binding” on
page 69. In the example show real server output shown above,
assume that port 70 is untranslated and follows the state of port
http. If the http port’s state changes, port 70’s state also changes
to match.
This field can have one of the following values for the types of ports
listed above:
•
1 – Enabled
•
2 – Failed
•
3 – Test
•
4 – Suspect
•
5 – Graceful shutdown
•
6 – Active
For all other types of ports, the value is always 0.
CurConn The number of client connections currently on the server. A connection
consists of two sessions, the client-to-server session and the
server-to-client session.
TotConns The number of client connections on the server since the Brocade
Virtual ADX was last booted. A connection consists of two sessions, the
client-to-server session and the server-to-client session.
Rx-pkts The number of packets the Brocade Virtual ADX has received from the
server.
Tx-pkts The number of packets the Brocade Virtual ADX has sent to the server.
Rx-octet The number of octets (bytes) the Brocade Virtual ADX has received from
the server.
Tx-octet The number of octets (bytes) the Brocade Virtual ADX has sent to the
server.
Reas The number of times the Brocade Virtual ADX has reassigned the
connection to another server in the rotation because the server that is in
use has not responded to two contiguous TCP SYNs from the client.
When this occurs, the Brocade Virtual ADX directs the client to another
server upon receiving the third SYN from the client.
NOTE: Windows 98 sends two TCP SYNs for each connection attempt.
NOTE: This statistic does not apply to Direct Server Return (Direct
Server Return).
