eG Monitoring
 
Measures reported by CssIfTest

The CSS forwards VLAN circuit traffic to the IP interface. The IP interface passes the traffic to the IP forwarding function where the CSS compares the destination of each packet to information contained in the routing table. The routing table typically contains the output interface and the next-hop address. Once the CSS resolves the packet addresses, it forwards the packet to the appropriate VLAN and destination port.

This test reports useful statistics related to the VLAN-VLAN communication that CSS enables via the IP interfaces configured on it.

 The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Reachroutes_memory Indicates the current number of reachable routes. Number  
Totalroutes_memory Indicates the total number of reachable routes during this measurement period. Number  
Reachhosts_memory Indicates the number of hosts that are currently reachable. Number  
Totalhosts_memory Indicates the total number of reachable hosts during this measurement period. Number  
Pool_memory Indicates the total amount of memory in bytes allocated for the IP routing table. Bytes When there are no additional free entries in the memory pool, more memory is allocated to the pool.
Redundant_state Indicates the current redundancy state of the monitored CSS. Number If this measure reports the value 1, it indicates the 'Init' state. The value 2 on the other hand, indicates the 'Backup' state.
Total_alive_uplinks Indicates the number of alive uplinks during this measurement period. Number Within a redundant configuration, CSS allows you to create one/more uplink services with a router's IP address. An uplink service enables the master CSS to monitor the router with a keepalive (ICMP). If the keepalive fails, the master relinquishes control and the backup CSS takes control. The master CSS uses all redundancy uplinks when making the failover decision.

If the value of this measure is 0, it indicates that there are no live uplink services. In such a case, the CSS goes into failover.
