3.2 Polling with the Corente MIB

3.2.1 Location Gateway Information

To view information about a specific Corente Services Gateway, you would poll CORENTE-MIB::corente and receive the following information about the Location gateway:

Table 3.1 Polling for Corente Services Gateway Information

Variable	Definition
gatewayDomain	The name of the domain in which the Location gateway exists.
gatewayName	The Gateway Name of the Corente Services Gateway.
gatewayConfig	The configuration type of the Corente Services Gateway or Corente Client (peer, inline, or client).
tunnelNumber	The number of tunnels that this Location gateway currently has.

Sample Poll Result:

enterprises.corente.gateway.gatewayDomain.0 = LargeCompany
enterprises.corente.gateway.gatewayName.0 = New_York
enterprises.corente.gateway.gatewayConfig.0 = inline
enterprises.corente.tunnels.tunnelNumber.0 = 2

3.2.2 Corente Tunnels

To view information about the tunnels of a Corente Services Gateway, you would poll Corente-MIB::tunnelTable and receive the following table with information about each tunnel that the Location gateway currently has to its partners:

Table 3.2 Polling for Information about a Corente Services Gateway's Tunnels

Variable	Definition
tunnelIndex	Reference number (row number) for the tunnel table.
tunnelPartnerName	The name of the partner.
tunnelPartnerConfig	The configuration type of the partner Location (peer, inline, native, or client).
tunnelStatus	The current status of the tunnel. TunnelUp: The tunnel is UP. TunnelDown: The tunnel is DOWN. TunnelPending: The tunnel is attempting to be established. TunnelConfigAlert: The tunnel has a configuration problem. TunnelConditional: The tunnel is PARTIALLY UP but has experienced an IPSEC subnet failure. TunnelAlert: The tunnel is DOWN and ALARMED due to LAN related problems. TunnelUnknown: The tunnel state is presently UNKNOWN.
tunnelUptime	The amount of time (in seconds) since the tunnel last came up.
tunnelCumUptime	The cumulative length of time (in seconds) that this tunnel has been up since the Location gateway was last started.
tunnelNatEffect	The NAT settings currently active on the tunnel. The possible values in this field are defined as follows: 0 – No NAT present 1 – Auto Resolve enabled 2 – Inbound NAT enabled 4 – Outbound NAT enabled 5 – Outbound NAT and Auto Resolve enabled 6 – Outbound and Inbound NAT enabled
tunnelTransport	The transport protocol used to encapsulate packets (TCP, UDP, or native).
tunnelTransKB	The number of kilobytes transmitted by the Location gateway since the tunnel started.
tunnelTransPkts	The number of packets transmitted by the Location gateway since the tunnel started.
tunnelRecvKB	The number of kilobytes received by the Location gateway from its partner since the tunnel started.
tunnelRecvPkts	The number of packets received by the Location gateway from its partner since the tunnel started.
tunnelErrors	The number of packets that had errors since the tunnel started.
tunnelDropped	Does not currently apply and is reserved for future use.
tunnelQueued	The number of packets that have been queued (delayed transmission) since the tunnel started. The size of the tcptd packet queue at the moment when the poll is processing. The "high-water mark" for the number of packets that have been queued for transmission since the tunnel started.
