8. In the Traceroute Criteria area, select Initiate Traceroute when criteria are met, and 

complete the following:

a. In the Number of Failed Hosts field, enter the number of hosts from the configured keep 

alive hosts that can fail to receive keep alive responses. If multiple hosts are configured 
and all hosts are critical, enter 1. If any one of the configured hosts failed to respond, 
network path failover occurs.

b. In the Consecutive “No”Responses field, enter the number of consecutive connectivity 

checks without a keep alive response before traceroute is initiated. The default is 10.

c. In the Target Host area, select the host type.

l

First Failed Host. The network host IP address specified in the keep alive host list. 
Traceroute will be initiated to the first failed host from the configured keep alive host 
list that meets the traceroute criteria.

l

Host IP. The network host IP address to monitor connectivity.Traceroute will be 
initiated on the specified host IP address.

d. Click Save.

If you are creating VPNs that use certificates for authentication and security, use the Policy 
Manager for My Certificates to install signed certificates into specific VSU.

After one or more certificates have been installed, see 

 about 

configuring a target for a signed certificate, and 

on page 238 about installing 

issuer certificates on a target.

VSUs use public-key certificates based on CCITT Recommendation X.509. Within the 
framework of the recommendation, each certificate includes a Rivest, Shamir, and Adleman 
(RSA) Public-Key Cryptography Standard (PKCS) Number 10 for authentication.

A VSU can store up to nine certificates. One is a default certificate which is only used for the 
SSL connection between the VSU and the VPNmanager Console. The remaining eight 
certificates are My Certificates and are statically stored in the flash memory of the VSU. The 
default certificate is issued by Avaya Inc..

Note:

The default certificate has a six year period of validity, which starts at the factory 
when it’s put into the VSU. Reprogramming the flash is the only way to change 
the default certificate.
