Nortel Networks TP-1610 SIP Configuring the Snmp Managers Table, Multiple Routers Support

Mediant 2000 SIP User’s Manual 5. Web Management

5.9.1.1Configuring the SNMP Managers Table

The SNMP Managers table allows you to configure the attributes of up to five SNMP managers.

To configure the SNMP Managers Table, take these 6 steps:

1.Access the ‘Network Settings’ screen (Advanced Configuration menu > Network Settings); the ‘Network Settings’ screen is displayed (Figure 5-14).

2.Open the SNMP Managers Table screen by clicking the arrow sign (-->) to the right of the SNMP Managers Table label; the SNMP Managers Table screen is displayed (Figure 5-15).

3.Configure the SNMP managers parameters.

4.Click the Submit button to save your changes.

5.Click the Close Window button.

6.To save the changes so they are available after a power fail, refer to Section 5.12 on page 84.

Note: If you clear a checkbox and click Submit, all settings in the same row revert to their defaults.

5.9.1.2Multiple Routers Support

Multiple routers support is designed to assist the media gateway when it operates in a multiple routers network. The gateway learns the network topology by responding to ICMP redirections and caches them as routing rules (with expiration time).

When a set of routers operating within the same subnet serve as gateways to that network and intercommunicate using a dynamic routing protocol (such as OSPF, etc.), the routers can determine the shortest path to a certain destination and signal the remote host the existence of the better route. Using multiple router support the media gateway can utilize these router messages to change its next hop and establish the best path.

Note: Multiple Routers support is an integral feature that doesn’t require configuration.

5.9.1.3Simple Network Time Protocol Support

The Simple Network Time Protocol (SNTP) client functionality generates requests and reacts to the resulting responses using the NTP version 3 protocol definitions (according to RFC 1305). Through these requests and responses, the NTP client is able to synchronize the system time to a time source within the network, thereby eliminating any potential issues should the local system clock 'drift' during operation. By synchronizing time to a network time source, traffic handling,
