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.
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.
