Cisco delivers 10 Gigabit Ethernet to the closet

Ready to roll

Try as I might, I couldn't get the Supervisor Engine II-Plus-10GE in the 4506 to stumble, even when presented with oversubscribed workloads and heavy QoS overhead. The port density offered by the 4506 chassis is substantial: My evaluation unit came with 48 10/100 copper ports, 48 SFP (Small Form-Factor Pluggable) 10/100 fiber ports, and 18 SFP/copper gigabit interfaces. The 4506 can handle a maximum of 240 gigabit copper interfaces, each supporting 802.3af power over Ethernet. Also, 240 gigabit fiber ports are supported, making the 4506 with the Supervisor Engine II-Plus-10GE a large distribution layer possibility.

With redundant 1,000W power supplies, the power consumption isn't as substantial as one might think -- and I ran all my tests using a single power supply.

For use in a redundant configuration, the Cisco 4507R chassis is required, and two Supervisor II-Plus-10GE supervisors may be used in a fail-over fashion. Although four 10-Gig ports are present between the two supervisors, only two may be utilized in this configuration.

The Supervisor Engine II-Plus-10GE supports CLI and SNMP management but doesn't support Web management of a useful sort. However, Cisco's Network Assistant will work with the Supervisor Engine II-Plus-10GE and provide SNMP-driven GUI management for most common functions, such as VLAN port changes and general switch management.

So, given a solid fiber plant, pushing 20Gbps each way to closets or other buildings on a campus or within a MAN (metropolitan area network) is easily possible with this switch. Cisco's Supervisor Engine II-Plus-10GE and the 4506 chassis are meant to perform some heavy lifting, and together they stand as another nail in the coffin for ATM as an enterprise interconnect.
