zxr10tcpConnState
Module: ZXR10-IP-VRF-ADDR-MIB
OID (symbolic): ZXR10-IP-VRF-ADDR-MIB::zxr10tcpConnState
OID (numeric): 1.3.6.1.4.1.3902.3.101.2.1.1.2
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: The state of this TCP connection.
The only value which may be set by a management station is deleteTCB(12). Accordingly, it is appropriate for an agent to return a `badValue' response if a management station attempts to set this object to any other value.
If a management station sets this object to the value deleteTCB(12), then this has the effect of deleting the TCB (as defined in RFC 793) of the corresponding connection on the managed node, resulting in immediate termination of the connection.
As an implementation-specific option, a RST segment may be sent from the managed node to the other TCP endpoint (note however that RST segments are not sent reliably).
What is zxr10tcpConnState?
This obsolete, read-write object reports the current state of a TCP connection (such as listen, established, or closeWait) following the standard RFC 793 TCP state machine, and accepts only the special value deleteTCB(12) as a set. It matters for diagnosing management-plane TCP sessions per VRF, and setting deleteTCB(12) forcibly terminates a connection stuck in a bad state. For example, an admin sets this object to deleteTCB(12) to kill a session hung in closeWait that a device otherwise won't release.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.3902.3.101.2.1.1.2 snmpwalk -v2c -c public <target> ZXR10-IP-VRF-ADDR-MIB::zxr10tcpConnState
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.3902.3.101.2.1.1.2.1 snmpget -v2c -c public <target> ZXR10-IP-VRF-ADDR-MIB::zxr10tcpConnState.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.3902.3.101.2.1.1.2.1 i <value>
