Jumbo Frames on NetScaler SDX Appliances
Apr 14 , 20 15
NetScaler SDX appliances support receiving and transmitting jumbo frames containing up to 9216 bytes of IP data. Jumbo
frames can transfer large files more efficiently than it is possible with the standard IP MT U size of 1500 bytes.
A NetScaler appliance can use jumbo frames in the following deployment scenarios:
Jumbo to Jumbo: T he appliance receives data as jumbo frames and sends it as jumbo frames.
Non-Jumbo to Jumbo: T he appliance receives data as non-jumbo frames and sends it as jumbo frames.
Jumbo to Non-Jumbo: T he appliance receives data as jumbo frames and sends it as non-jumbo frames.
T he NetScaler instances provisioned on NetScaler SDX appliance support jumbo frames in a load balancing configuration
for the following protocols:
T CP
Any other protocol ove T CP
SIP
For more information about jumbo frames, see the use cases.
Use Case: Jumbo to Jumbo Setup
Updated: 2015-02-06
Consider an example of a jumbo to jumbo setup in which SIP load balancing virtual server LBVS-1, configured on NetScaler
instance NS1, is used to load balance SIP traffic across servers S1 and S2. T he connection between client CL1 and NS1, and
the connection between NS1 and the servers support jumbo frames.
Interface 10/1 of NS1 receives or sends traffic from or to client CL1. Interface 10/2 of NS1 receives or sends traffic from or
to server S1 or S2. Interfaces 10/1 and 10/2 of NS1 are part of VLAN 10 and VLAN 20, respectively.
For supporting jumbo frames, the MT U is set to 9216 for interfaces 10/1, 10/2, and VLANs VLAN 10, VLAN 20.
All other network devices, including CL1, S1, S2, in this setup example are also configured for supporting jumbo frames.
T he following table lists the settings used in the example.
