The 7705 SAR-A, 7705 SAR-Ax, 7705 SAR-M, 7705 SAR-H, 7705 SAR-Hc, and 7705 SAR-Wx support user-configurable fabric shapers at rates of up to 5 Gb/s for access ingress and network ingress traffic. The fabric interface on these nodes is a shared resource between both traffic types, and one buffer pool serves all MDAs (ports).
These nodes do not support fabric profiles; instead, they have a single aggregate rate limit for restricting access traffic into the fabric and a single aggregate rate limit for restricting network traffic into the fabric. These limits apply to all MDAs. Both access ingress and network ingress traffic can be configured to shaping rates of between 1 kb/s and 5 Gb/s. The default rate for access ingress traffic is 500 Mb/s. The default rate for network ingress traffic is 2 Gb/s. Statistics can be viewed for aggregate access and network traffic flow through the fabric and possible discards.
The 7705 SAR-X fabric shaper rate is not configurable for access ingress or network ingress traffic, and is set to the maximum rate for the platform. There are three buffer pools on the 7705 SAR-X, one for each MDA (block of ports).
