Brocade do, but no 10Gbps port density.

As I stated last week, such a model might be available some day.

I have been curious about the cisco catalyst 6800 line… seems that the 6840 might fit this realm of smaller mpls pe… not sure of price…

The Cat6k including 6840 can certainly do a fair number of MPLS
features, we use their older brother (6880, sup2T) and for a little
while longer predecessor (sup720) as MPLS PE in L3VPN (inc. 6vPE), MVPN
and some small amount of L2VPN (mainly EoMPLS)

IIUC the layer2 and MVPN stuff is lagging the state of the art quite a
bit on that software train, which might be an issue for you.

The per-port cost will be relatively high compared to a merchant
silicon-based device, but the features tend to be a bit better. Port
density is also kind of low on the cat6k sadly.

They also run plain old IOS, with it's paucity of modern comforts (like
any form of API, or transactional commits, etc.). Slightly weedy CPU,
especially if you use Netflow on them (do not get me started...)

Egress policing and other advanced QoS features also used to be a big
problem on this platform and its cousins, but I believe this has since
been fixed for the SUP-2T as well as the current generation boxes in
this portfolio.

Brocade is using Broadcom chips as well right? Or are they using their own chips in some of the boxes?

The last time I tested the NetIron's, it was their own silicon.

Aaron,

Have you tested any of the OAM features on the ACX5048 like Y.1564,
802.3ah, 802.1ag, Y.1731, Two-Way Active Measurement Protocol (TWAMP) and
RFC2544? Do you have smaller ACX's like the 2200 connected to the ACX5048?
Are you using Juniper MX routers in your network as well?

Hi Colton,



Q1 - Have you tested any of the OAM features on the ACX5048 like Y.1564, 802.3ah, 802.1ag, Y.1731, Two-Way Active Measurement Protocol (TWAMP) and RFC2544?



A1 – no, but we do have a CFM effort underway for getting to know CFM better and understand how to architect network-wide CFM domains/levels, mips, meps, up, down all that stuff…. So perhaps later I would be able to speak to this.



Q2 - Do you have smaller ACX's like the 2200 connected to the ACX5048?



A2 – I have no other acx’s. I only have acsx5048’s. (I do have some ex4550’s virtual chassis’d together as ToR switches in my 2 small datacenters and they are not connected to acx5048’s…. at least at the moment)



Q3 - Are you using Juniper MX routers in your network as well?



A3 – not at the moment. Only in the lab. I have one mx104 testing cgnat. If I decide on the juniper solution for cgnat then I might go with mx104 or mx240/480 with ms-mpc licensed npu’s. (I have vMX in GNS3 virtual environment)



….who knows, maybe when we begin planning the increase of our 20 gbps asr9k cisco ring, we may consider mx480’s there too.

Wondering why no one mentioned ASR903 with RSP3.

It can do 100GE per slot (8x10Ge/2x40GE/1x100GE) and there are 6 slots.
Two RSPs two PSUs (only FAN tray is single point of failure).
And feature wise it should do everything that ASR920 does.

Compared to Juniper the only drawback is the FIB scale which apparently is just 192,512 IPv4 routes.
-I guess the reason behind this is that if they would increase that it would compete with ASR9K line.

Adam,

I think because of the price point of the ASR903 just is not there. These
Juniper ACX5048's can be bought for under $5,000 new. The ASR903 with a
hefty discount was in the $15k range with like one line card. Even if you
fully populated the 903 it wouldn't have the same amount of ports as a
ACX5048. It would have more redundancy, and the ability to have a 100G
uplinks however.
