Enabling Private and Failover Mode
To temporarily enable (or change) jumbo frame support for an hxge network interface, use an ifconfig ethn mtu nnn command. You can do this while the interface is up and running (and actively passing network traffic), but if you set the maximum frame size to a smaller value, you might disrupt incoming traffic from other nodes that are using an older (larger) value.
host #> ifconfig eth2 eth2 Link encap:Ethernet HWaddr 00:14:4F:29:00:1D inet addr:10.1.10.156 Bcast:10.1.10.255 Mask:255.255.255.0 inet6 addr: fe80::214:4fff:fe29:1/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:1 errors:0 dropped:0 overruns:0 frame:0 TX packets:30 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:150 (150.0 b) TX bytes:7850 (7.6 KiB) Memory:fb000000-fc000000
Note that in this example, eth2 (the NEM from previous examples) is currently running with the standard MTU of 1500 bytes.
host #> ifconfig eth2 mtu 9000
host #> ifconfig eth2 eth2 Link encap:Ethernet HWaddr 00:14:4F:29:00:01 inet addr:10.1.10.156 Bcast:10.1.10.255 Mask:255.255.255.0 inet6 addr: fe80::214:4fff:fe29:1/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:9000 Metric:1 RX packets:26 errors:0 dropped:0 overruns:0 frame:0 TX packets:40 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:3900 (3.8 KiB) TX bytes:9352 (9.1 KiB) Memory:fb000000-fc000000
Note that ifconfig now reports the MTU size to be 9000 bytes. NFS 8KB pages will now flow (send or receive) as a single Ethernet packet.
