10.3Communication Configuration

SNMP Communication Configuration is only accessible via the web interface.

Select Configure SNMP from CXC web interface Communications menu as shown below.

10.3.1 SNMP Multiple Community Names

This menu item enables the User to configure multiple CXC SNMP community settings for get (read) and set (write). This is to permit multiple SNMP NMS programs, with different community strings, to connect to the CXC.

NOTE: Before this feature, the CXC had one set of community strings, which meant that any NMS that tried to connect to the CXC must be a match.

Now, a company with multiple NMS's, each in a different region, with a different community string, will find it easier to connect to the CXC from various places. See Figure below:

Figure 117–SNMP Community Name web interface window

10.3.2SNMP Trap Recovery

This feature enables the CXC SNMP agent to hold traps in a buffer during a network block out period. The master network management station (NMS) must be monitoring (polling) the SNMP agent in order for the agent to resend the traps after the network connection has again been established.

NOTE: The following items along with any item from the Argus MIB will reset the poll timer:

•sysDescr.0

•sysContact.0

•sysName.0

•sysLocation.0

An ICMP7 echo request packet or “ping” is used to determine whether a trap may be received (recovered) by the SNMP client. Once successful, the trap is sent.

The time-out before failure of ping has been increased from two seconds to eight.

NOTE: Master NMS destination can be selected from Master SNMP Destination pull-down menu (see next section Event Notification).
