Each list displays the uplink port and the percentage of that port’s bandwidth that was utilized by
the downlink ports over the most recent 30-second interval. You can configure up to four
bandwidth utilization lists.
To configure a link utilization list with port 1 as the uplink port and ports 2 and 3 as the downlink
ports, enter a command such as the following.
ServerIronADX(config)# relative-utilization 1 uplink eth 1 downlink eth 2 to 3
Syntax: [no] relative-utilization <num> uplink ethernet <portnum> [to <portnum> | <portnum>…]
downlink ethernet <portnum> [to <portnum> | <portnum>…]
The <num> parameter specifies the list number. You can configure up to four lists. Specify a
number from 1 – 4.
The uplink ethernet parameters and the port number(s) you specify after the parameters indicate
the uplink port(s).
The downlink ethernet parameters and the port number(s) you specify after the parameters
indicate the downlink port(s).
Displaying an uplink utilization list
Displaying an uplink utilization list allows you to observe the percentage of the uplink’s bandwidth
that each of the downlink ports used during the most recent 30-second port statistics interval. The
number of packets sent and received between the two ports is listed, as well as the ratio of each
individual downlink port’s packets relative to the total number of packets on the uplink.
To display an uplink utilization list, enter a command such as the following.
ServerIronADX(config)# show relative-utilization 1
uplink: ethe 1
30-sec total uplink packet count = 3011
packet count ratio (%)
1/ 2:60 1/ 3:40
In this example, ports 2 and 3 are sending traffic to port 1. Port 2 and port 3 are isolated (not
shared by multiple clients) and typically do not exchange traffic with other ports except for the
uplink port, port 1.
Syntax: show relative-utilization <num>
The <num> parameter specifies the list number.
Setting system time and date
You can set the system time and date for a ServerIron ADX.
Clock settings are saved over power cycles. You can also configure the system to reference a SNTP
server at power up. This server will then automatically download the correct time reference for the
network. For more details on this capability, reference the sntp command at the privileged EXEC
level and the sntp poll-interval and sntp server commands at the global CONFG level.
To set the system time and date for a ServerIron ADX, enter a command such as the following.
ServerIronADX# clock set 10:15:05 10-15-98
Syntax: [no] clock set <hh:mm:ss> <mm-dd-yy> | <mm-dd-yyyy>
To set the time zone, use the clock timezone command at the global configuration level.
