Hello we are measuring FCIP transfer rate by polling the subject MIB objects every 5 minutes and calculate the delta (devided by 300secs). .An FCIP tunnel VE16 involves only one circuit on ge0 in our configuration so I thought that ifHCOut/InOctets for VE16 and ge0 would be the same but these objects for ge0 always show higher transfer rate than those forVE16 in our installation and here are my questions:
Q1. Why (in our installation) ge0 has higher transfer rate than VE16?
I am coming to assume that the transfer bytes at VE level dooes not take accouunt TCP/IP headers while the transfer bytes for ge0 does take account these headers. Can somebody endorse me or explain?
Q2. Sometimes I see the calculated transfer late (for VE) is over 1GB/sec that cannot happen as we use 10GbE (i.e., 10Gbps hence 1GB/sec for 8B/10B) we would like to know the reason for that.
An examplle of actual calculated value is about 1.07GB/sec which is too big to quote 'it is within an error range at the given interval'....
Many thanks in advance!!

excepted you don't have Gen6 SX6 Extension Blade, where all features are enable in FOS 8.x by default;
can you please specified the type of hardware and license ?
is a FX8-24 Blade or 7840 ?

I appreciate you for the prompt response on this topic.
My apologies for not including hardware/license information.
Our installation uses SAN06B-Rs(or 7800s) which is:
We do *not* have or use advanced extension license..
Hope the above helps understand our installation.

My apologies but I took the interface wrong.. As we are using SAN06B-R(7800), the network interface is GbE and NOT 10GbE so the Q2 above should read::
Q2. Sometimes I see the calculated transfer late (for VE) is over 100MB/sec that cannot happen as we use GbE (i.e., 1Gbps hence 100MB/sec for 8B/10B) we would like to know the reason for that.
An examplle of actual calculated value is about 107MB/sec which is too big to quote 'it is within an error range at the given interval'....
Again, sorry for the confusion that might have caused.
