Cisco Cisco Packet Data Gateway (PDG)

 

There are multiple StarOS commands to verify and/or troubleshoot network connectivity of the target VPC-VSM 
instance. Note that network connectivity can only be tested only after VM interfaces and ports have been configured and 
bound. 

The commands specified in this section should be issued on a context-by-context basis. Contexts act like virtual private 
networks (VPNs) that operate independently of other contexts. Ports, interfaces, and routes configured in one context 
cannot be tested from another context without additional configuration. 

To switch between contexts enter the following command at the root prompt for the Exec mode: 

context context_name 

context_name is the name of the context to which you wish to switch. The following prompt appears: 

[context_name]host_name# 

The ping or ping6 command verifies the system’s ability to communicate with a remote node in the network by passing 
data packets between and measuring the response. This command is useful in verifying network routing and if a remote 
node is able to respond at the IP layer. 

The ping command has the following syntax: 

ping host_ipv4_address [ count num_packets ] [ flood ] [ pattern packet_pattern ] 
[ size octet_count ] [ src { src_host_name | src_host_ipv4_address } ] [ vrf 
vrf_nam ] 

ping6 host_ipv6_address [ count num_packets ] [ flood ][ pattern packet_pattern ] 
[ size octet_count ] [ src { src_host_name | src_host_ipv6_address } ] [ vrf 
vrf_nam ] 

For complete information regarding the above commands, see the Exec Mode Commands chapter of the Command line 
Interface Reference. 

The following displays a sample of a successful ping (IPV4) response.
