WS-X4515 Cisco Catalyst 4000 and 4500 Supervisor Engine IV

The WS-X4515 is the Cisco Catalyst 4000 Supervisor Engine IV. It integrates Layer 2, 3 and 4 switching on one centralized engine with a 64-Gbps nonblocking switch fabric, and forwards 48 Mpps at Layer 2 and 48 Mpps at Layer 3/4 in hardware, including IP routing based on Cisco Express Forwarding. It runs only Cisco IOS Software, not CatOS.

Two 1000-Mbps Gigabit Ethernet uplinks use GBIC interfaces. The module has a 333 MHz CPU, 512 MB of SDRAM running at 133 MHz, 512 kB of NVRAM, 64 MB of onboard flash and 16 MB of shared packet memory. A removable CompactFlash card of 64 MB or 128 MB is available as MEM-C4K-FLD64M or MEM-C4K-FLD128M. Power consumption is 100 W.

The supervisor fits the Catalyst 4006, 4503, 4506 and 4507R chassis. Redundant operation applies only to the 4507R, where supervisors occupy slots 1 and 2, the secondary monitors the primary and takes over if it fails, and supervisors are hot-swappable. WS-X4515/2 is the Catalyst 4507R Redundant Supervisor Engine IV.

Other limits are 4096 VLANs, 32,768 MAC addresses and 131,072 routing entries, with four queues per port and per-port QoS. Hardware handles IGMP snooping, PIM, SSM and ACLs. Basic Layer 3 software is S4KL3-12112EW and enhanced Layer 3 software with OSPF, IGRP and EIGRP is S4KL3E-12112EW, both with a minimum version of 12.1(12c)EW.
