The multi-service-2 parameter provides another alternative to multi-service to optimize the device
for Multi-Service applications.
The multi-service-3 parameter provides another alternative to multi-service to optimize the device
for Multi-Service applications to support IPv6 VRF.
The multi-service-4 parameter provides another alternative to multi-service to optimize the device
for Multi-Service applications to support IPv6 VRF.
CAM partition profiles for the Brocade NetIron XMR and Brocade MLX series
Not all CAM profiles are compatible for running Layer 2 switching and configuring GRE tunnels
simultaneously on a Brocade device.
Configuring the maximum number of tunnels supported
You can configure the devices to support a specified number of tunnels using the following
command.
Brocade(config)# system-max ip-tunnels 512
Brocade(config)# write memory
Syntax: system-max ip-tunnels number
The number variable specifies the number of GRE tunnels that can be supported.
The Brocade NetIron XMR and Brocade MLX series permissible range is 1 - 8192. The default value
is 256. The permissible range for Brocade NetIron CES devices is 32 - 128. The default value is 32.
The permissible range for Brocade NetIron CER devices is 32 - 256. The default value is 32.
NOTE
Multicast over GRE tunnels for PIM can support up to the default system max of 256 tunnels if the
required hardware resources are available.
NOTE
You must write this command to memory and perform a system reload for this command to take
effect.
