[f-nsp] Features on Brocade Ethernet platforms

[Robert Hass]

Hi

I'm leading project where we would like to migrate customer's D-Link
switches (6 core nodes, around 30 access) + Linux routers (6 PEs - BGP
+ OSPF) network into new hardware solution. Goal is to replace all
equipment and upgrade existing 4Gbps (4x1Gbps LACP) backbone links
into 10GE links. We considering now few vendors - and Brocade here
looks very promising but we don't have much experience with this
equipment. So I have couple of questions related to Brocade gear.

1) CER as PE router

Which is below features is supported on CER 2000 platform:

- SNMP Counters on VE interfaces
- Inter-Operability with Cisco VTP
- Port Monitoring Local Destination
- Port Monitoring Remote (RSPAN)
- Spanning-Tree BPDU Filter support
- Ingress Shaping/Policing on physcial interfaces
- Ingress Shaping/Policing on VE interfaces
- Ingress Shaping/Policing on L2 VLANs
- Egress Shaping/Policing on physcial interfaces
- Egress Shaping/Policing on VE interfaces
- Egress Shaping/Policing on L2 VLANs
- IPv4/IPv6 FIB import filter (eg. we have full bgp table in RIB, but
partial in FIB - filtering via route-map, prefix-lists etc.)
- DDoS ControlPlane protection (like CoPP on Cisco, or Loopback
inbound ACL for protect RE on Junipers)
- Port Security (max MAC addresses)
- Broadcast/Multicast storm control - configured in pps
- QoS Marking
- QoS Scheduling (assigning cos/dscp to specific queue)
- QoS Scheduling per port
- QoS Strict-Priority Queue
- ECMP L2 (LAG) Hashing (src-dst-ip or src-dst-mixed-ip-port)
- ECMP L3 (L3 equal cost routing) (src-dst-ip or src-dst-mixed-ip-port)
- NetFlow v5
- NetFlow v9
- sFlow
- VTPv2 / VTPv3
- DOM for OEM 1G/10G optics
- Mixed (DC+AC) Power Supply Option

2) TurboIron 24X - as core platform

Is this switch is good solution to pure 10GE core ? We want use them for :
- interconnect to other core nodes by 1x10GE and 2x10GE LAGs
- interconnect to upstream providers (eg. GlobalCrossing, KPN and DE-CIX)
- downlinks to PE routers by 2x10GE LAGs
- downlinks to access switches (customer access switches)
- at core we transporting multicast with IPTV (around 900Mbps) it will
be not problem ? (eg. with microbursts at core)
- is SFP+ ER (40KM) 1550nm is supported in this switch ?
- is QinQ supported on this switch ?

If TurboIron is not good idea here then what we should consider as
alternative ? MLX/RX is not option here as It's too expensive. We need
just 8 x 10GE ports (best if XFP, but SFP+ is fine with us too).

3) FCX624 - as one of access-switches

- can we do ingress/egress policing on GE ports on this switch ?
- can we do ingress/egress policing on specified VLANs on 802.1q trunk
ports ? (eg. I have trunk with VLAN 100,101,102 - and I would like to
police VLAN 100 to 20Mb, VLAN 101 to 40Mb, and do not police VLAN 102)
- optional module FCX-4XG as I see is providing 4 x 10GE SFP+ ports,
will SFP+ ER (40KM) 1550nm work with this module ?
- how deep buffers it has (eg. microbursts problem)

4) Other L2 platforms - which other Brocade 1U switch has deep buffers
and 2x10GE capability ? I also need QinQ, Ingress/Egress policing at
GE/VLANs ports.

Thanks a lot,
Robert
