npCfgTcpMss
Module: JETDIRECT3-MIB
OID (symbolic): JETDIRECT3-MIB::npCfgTcpMss
OID (numeric): 1.3.6.1.4.1.11.2.4.3.5.11
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Enumerate as follows: 0 = treat all hosts as local which means JetDirect sends a maximum of 1460 bytes of data in all outbound packets. 1 = treat hosts on different subnets but in the same network as local which means for hosts in the same network, send 1460 bytes; else send 536 bytes in outbound packets. 2 = treat only hosts on the same network and same subnet as local (use 1460 bytes); otherwise treat them as remote hosts (send 536 bytes).
What is npCfgTcpMss?
Controls the maximum TCP segment size used for outbound packets: 0 treats all hosts as local and sends up to 1460 bytes, 1 sends 1460 to hosts in the same network and 536 otherwise, 2 sends 1460 only to hosts on the same network and subnet and 536 to the rest. Raising to local-like behavior helps throughput; use 2 when routers cannot cope with large segments.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.11.2.4.3.5.11 snmpwalk -v2c -c public <target> JETDIRECT3-MIB::npCfgTcpMss
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.11.2.4.3.5.11.1 snmpget -v2c -c public <target> JETDIRECT3-MIB::npCfgTcpMss.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.11.2.4.3.5.11.1 i <value>
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> npCfgTcpMss.1
