2 open mini-GBIC (SFP) slots
1 RJ-45 serial console port
Power over Ethernet (PoE) :
IEEE 802.3af Power over Ethernet (PoE): provides up to 15.4 W per port to IEEE 802.3af-compliant PoE-powered devices such as IP phones, wireless access points, and security cameras
IEEE 802.3at Power Over Ethernet Plus: provides up to 30 W per port to IEEE 802.3 for PoE-/PoE+-powered devices such as video IP phones, IEEE 802.11n wireless access points, and advanced pan/tilt/zoom security cameras
Layer 2 switching :
VLANs: provide support for 512 VLANs and 4,094 VLAN IDs
Jumbo packet support: supports up to 9220-byte frame size to improve the performance of large data transfers
IEEE 802.1v protocol VLANs: isolate select non-IPv4 protocols automatically into their own VLANs
Layer 3 routing :
Static IP routing: provides manually configured routing; includes ECMP capability
Routing Information Protocol (RIP): provides RIPv1 and RIPv2 routing
Performance :
100 Mb Latency < 8.3 μs (LIFO 64-byte packets)
1000 Mb Latency < 2.9 μs (LIFO 64-byte packets)
Throughput up to 9.5 million pps
Switching capacity 12.8 Gbps

Quality of Service (QoS) :
Layer 4 prioritization: enables prioritization based on TCP/UDP port numbers
Traffic prioritization (IEEE 802.1p): allows real-time traffic classification into eight priority levels mapped to eight queues
Class of Service (CoS): sets the IEEE 802.1p priority tag based on IP address, IP Type of Service (ToS), Layer 3 protocol, TCP/UDP port number, source port, and DiffServ
Rate limiting: sets per-port ingress enforced maximums and per-port, per-queue guaranteed minimums
Resiliency and high availability :
External redundant power supply: provides high reliability
IEEE 802.3ad Link Aggregation Protocol (LACP) and HP port trunking: support up to 24 trunks, each with up to 8 links (ports) per trunk
IEEE 802.1s Multiple Spanning Tree: provides high link availability in multiple VLAN environments by allowing multiple spanning trees
Manageability :
Dual flash images: provides independent primary and secondary operating system files for backup while upgrading
Friendly port names: allow assignment of descriptive names to ports
Find-Fix-Inform: finds and fixes common network problems automatically, then informs administrator
Multiple configuration files: allow multiple configuration files to be stored to a flash image
RMON, XRMON, and sFlow: provide advanced monitoring and reporting capabilities for statistics, history, alarms, and events
