We are proposing to install SIP-400's into our PE's 7600 (sup32) in order to provide egress traffic shaping and qos for our customers.
We are proposing to connect the SIP gig interfaces back to another line card on the same device, instead of putting another switch in front of our existing PE. This saves us a switch and lets us take advantage of the port density in our current 7600 PE's (which is why we purchased them in the first place).
We also plan to utilise the same approach to implement pwe xconnects on the SIP-400 subinterfaces. VLAN uniqueness per port is the key feature of the SIP-400 that facilitates this.
Has anyone run a similar setup? Any experiences to share?
I have tested in the lab and can't see any issues so far.
Does anyone know of a more cost effective qos / shaping solution for Ethernet tails? The SIP or ES20 based solutions seem overpriced for the pretty basic functionality we are after here. Doesn't have to be a Cisco box.
