Access Control Lists
(Toggle)
Enable or disable ACL to restrict SNMP/IP access to a limited number
of IP addresses. This field toggles between ENABLED and
DISABLED. DISABLED is the default setting.
When ACL is enabled, all device access is limited to the single 16 IP
addresses and/or range of IP addresses as shown in the previous screen
example (Figure 4-10). The limited access applies to all IP access
including, but not limited to, SLIP/PPP connections, Telnet, Ping,
SNMP and HTTP. When locally connected to the COM port of the host
device, ACL does not restrict access to local management.
ACL cannot be enabled unless a valid IP address is listed.
When ACL is disabled, host access is not restricted to the devices with
an IP address in the Access Control List.
IP Addr
(Modifiable)
Enter a new IP address of the devices that you want to have access to
SNMP/IP management. The default value is “0.0.0.0”.
Up to 16, individual user IP addresses and/or range of user IP addresses
can be entered. For individual IP address settings, the mask value must
be “255.255.255.255”.
For a range of IP addresses, both the IP address and appropriate Mask
value must be entered to indicate the range of IP addresses.
Only a user with a Super User status can view and modify the ACL.
NOTE: Clearing NVRAM will remove all IP address entries
and return the access control state to DISABLED.
For details on entering IP addresses, refer to Section 4.6.1.
