Command Usage

• You can create a list of up to 16 IP addresses or IP address groups that are

allowed access to the switch via SNMP management software.

• Address bitmasks are similar to a subnet mask, containing four decimal

integers from 0 to 255, each separated by a period. The binary mask uses “1”
bits to indicate “match” and “0” bits to indicate “ignore.”

• If the IP is the address of a single management station, the bitmask should be

set to 255.255.255.255. Otherwise, an IP address group is specified by the
bitmask.

• The default setting is null, which allows all IP groups SNMP access to the

switch. If one IP address is configured, IP filtering is enabled and only
addresses in the specified IP group will have SNMP access.

• IP filtering does not affect management access to the switch using the web

interface or Telnet.

Example
The following example enables SNMP IP filtering on the switch and allows SNMP
management access to client IP 10.1.2.3, and client IP group 10.1.3.0 to 10.1.3.255.

DHCP Commands

These commands are used to configure Dynamic Host Configuration Protocol
(DHCP) client, relay, and server functions. You can configure any VLAN interface to
be automatically assigned an IP address via DHCP. This switch can be configured to
relay DHCP client configuration requests to a DHCP server on another network, or
you can configure this switch to provide DHCP service directly to any client.

DHCP Client

Console(config)#snmp ip filter 10.1.2.3 255.255.255.255
Console(config)#snmp ip filter 10.1.3.0 255.255.255.0
Console(config)#
