Disable tunnel acceleration for GRE, VXLAN, and GTP-U
tunnels to troubleshoot.
By default, supported firewalls perform tunnel acceleration to
improve performance and throughput for traffic going through GRE
tunnels, VXLAN tunnels, and GTP-U tunnels. Tunnel acceleration provides
hardware offloading to reduce the time it takes to perform flow
lookups and allows the tunnel traffic to be distributed more efficiently
based on the inner traffic.
GRE and VXLAN tunnel acceleration
is supported on PA-3200 Series firewalls, PA-5450 firewalls, and
PA-7000 Series firewalls with PA-7000-100G-NPC-A and PA-7050-SMC-B
or PA-7080-SMC-B. You can disable tunnel acceleration to troubleshoot.
When you disable tunnel acceleration, you are doing so for GRE,
VXLAN, and GTP-U tunnels simultaneously.
There is no
performance impact for GRE traffic when disabling tunnel acceleration
if no tunnel content inspection (TCI) policies are being used.
