If you wish to force the CMM4 to a speed or duplex state, or to return
the module to auto-negotiating speed and duplex state, change the
selection for the port. The range of selections is defined below:
Table 17 Link Speed selections for CMM4
Selection
Result
Auto Negotiation
The CMM4 attempts to auto-negotiate speed and
duplex state.
(This is the default and recommended setting for most
network configurations.)
10Base T Half
Duplex
The CMM4 is forced to 10 Mbps and half duplex.
10Base T Full
Duplex
The CMM4 is forced to 10 Mbps and full duplex.
100Base T Half
Duplex
The CMM4 is forced to 100 Mbps and half duplex.
100Base T Full
Duplex
The CMM4 is forced to 100 Mbps and full duplex.
If you change this value for a port and then click Save Changes, the
change becomes effective immediately and the previous value is lost.
IP Access Control
You can permit access to the CMM4 from any IP address (IP Access
Filtering Disabled) or limit it to access from only one, two, or three IP
addresses that you specify (IP Access Filtering Enabled). If you select
IP Access Filtering Enabled, then you must populate at least one of the
three Allowed Source IP parameters or have no access permitted from
any IP address, including access and management by Prizm.
Allowed Source IP
1 to 3
If you selected IP Access Filtering Enabled for the IP Access Control
parameter, then you must populate at least one of the three Allowed
Source IP parameters or have no access permitted to the CMM4 from
any IP address. You may populate as many as all three.
