The components of SNMP network management fall into three categories:
1. Managed devices (such as a switch)
2. SNMP agents and MIBs, including Remote Monitoring (RMON) MIBs, which run on managed devices
3. SNMP management applications, such as CiscoWorks2000, which communicate with agents to get statistics
and alerts from the managed devices.
Note: An SNMP management application, together with the computer it runs on, is called a network management
system (NMS).
Read only community
The SNMP Read-only Community string is like a user id or password that allows access to a router's or other device's
statistics. InterMapper sends the community string along with all SNMP requests. If the community string is correct, the
device responds with the requested information. If the community string is incorrect, the device simply discards the
request and does not respond.
Factory default setting for the read-only community string is set to "public". It is standard practice to change all the
community strings so that outsiders cannot see information about the internal network. (In addition, the administrator
may also employ firewalls to block any SNMP traffic to ports 161 and 162 on the internal network.)
Change this value to have InterMapper use the new string when querying SNMP devices.
Read/Write community
Gives read and write access to all objects in the MIB, but does not allow access to the community strings
IP Information
IP Address Mode
•
Static
Manually setup an IP for this device.
o
•
DHCP
Set up the bridge as a DHCP client which will pick up an IP from a DHCP server.
o
IP address
The default Client Bridge Mode IP address: 192.168.1.99
Subnet mask
The factory subnet default value is 255.255.255.0
Gateway
The factory gateway default address is 192.168.1.1
Device name
This is the name that the bridge will use to identify itself to external configuration and IP address programs. This is not
the same as the SSID. It is okay to leave this blank if you are not using these programs.
Allow upgrade uploads
This option determines if the EzBridge can be re-flashed with a firmware into the on board memory.
