Filtering Addresses for SNMP Client Access
The switch allows you to create a list of up to 16 IP addresses or IP
address groups that are allowed access to the switch via SNMP
management software (also see page 3-69).
Command Usage
• To specify the clients allowed SNMP access, enter an IP address along
with a subnet mask to identify a specific host or a range of valid
addresses. For example:
- IP address 192.168.1.1 and mask 255.255.255.255 –
Specifies a valid IP address of 192.168.1.1 for a single client.
- IP address 192.168.1.1 and mask 255.255.255.0 –
Specifies a valid IP address group from 192.168.1.0 to
192.168.1.254.
• IP filtering only restricts management access for clients running SNMP
management software such as HP OpenView. It does not affect
management access to the switch using the web interface or Telnet.
• The default setting is null, which allows all IP groups SNMP access to
the switch. If one or more IP addresses are configured, IP filtering is
enabled and only addresses listed in this table will have SNMP access.
Command Attributes
• 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, set the mask to
255.255.255.255. Otherwise, an IP address group will be specified by
any other mask.
