IP Filtering

On the SNMP/IP Filtering page, you can create a list of up to 16 IP

addresses or IP address groups that are allowed access to the switch using

SNMP management software.

IP addresses that are permitted SNMP access are specified by an IP address

and a subnet mask that identifies the range of valid addresses. For example:

IP address 192.168.1.1 and mask 255.255.255.0 — Specifies a valid IP

address group from 192.168.1.0 to 192.168.1.255.

IP address 192.168.1.1 and mask 255.255.255.255 — Specifies a valid IP

address of 192.168.1.1 only.

The following options are available:

IP Filter List — Displays a list of the IP address/subnet mask entries

•

currently configured for SNMP access.

•

IP address — Specifies a new IP address to add to the IP Filter List.

Subnet Mask — Specifies a single IP address or group of addresses. If

•

the IP is the address of a single management station, the mask should

be set to 255.255.255.255. Otherwise, the IP address group is specified

by the mask.

Addendum to the 3 248 and 52 24 User 's Guides

NOTE: IP filtering does

not affect management

access to the switch using

the Web interface or

Telnet.
