• Secures a port to an individual MAC address group of

up to 132 MAC addresses; addresses can be learned or

manually entered; can prevent unauthorized stations

from accessing the switch.

• Password-protected in-band and out-of-band

management provides protection against unauthorized

configuration changes and secures against unwanted

intruders. Provides administrators the choice of level of

security, notification, and resulting actions.

• TACACS+ authentication enables centralized control of

the switch and restricts unauthorized users from altering

the configuration.

• Private VLAN Edge provides security and isolation

between ports on a switch, ensuring that voice traffic

travels directly from its entry point to the aggregation

device through a virtual path and cannot be directed to

a different port.

• Support for the optional Cisco 600-watt redundant

AC power system provides a backup power source

for up to four units for improved fault tolerance and

network uptime.

• Multilevel security on the console access prevents

unauthorized users from altering the switch

configuration.

• Cisco Uplink Fast technology ensures quick failover

recovery, enhancing overall network stability and

reliability.

• Cross-stack Uplink Fast (CSUF) technology provides

increased redundancy and network resiliency through

fast spanning-tree convergance (less than 2 seconds)

across a stack of switches using Gigastack GBICs.

• Redundant stacking connections support a redundant

loopback connection in top and bottom switches in

a stack.

• Command Switch Redundancy allows customers to

designate a backup command switch, which takes over

cluster management functions in the event of a failure of

the primary command switch.

• Unidirectional Link Detection (UDLD) detects and

disables unidirectional links caused by incorrect wiring

or interface faults, preventing Spanning Tree loops.

• 3.2 Gbps switching fabric

• 3.0 million-pps forwarding rate for 64-byte packets

• 1.6 Gbps maximum forwarding bandwidth

• 4-MB shared-memory architecture shared by all ports

• Packet forwarding rate for 64-byte packets:

– 14,880 pps to 10-Mbps ports

– 148,800 pps to 100BaseT ports

• 8-MB DRAM and 4-MB Flash memory

• 8192 MAC addresses

• SNMP Management Information Base (MIB) II, SNMP

MIB extensions, Bridging MIB (RFC 1493)

• IEEE 802.3x full duplex on 10Base-T and

100Base-T ports

• IEEE 802.1D Spanning-Tree Protocol

• IEEE 802.3u 100Base-TX and 100Base-FX specification

• IEEE 802.3 10Base-T specification

• IEEE 802.3z

• IEEE 802.3ab

• 10Base-T ports: RJ-45 connectors; two-pair Category 3,

4, or 5 unshielded twisted-pair (UTP) cabling

• 100Base-TX ports: RJ-45 connectors; two-pair

Category 5 UTP cabling

• Management console port: RJ-45 connector

• Per-port status LEDs—link integrity, disabled, activity,

speed, and full-duplex indications

• System status LEDs—system, RPS, module status, and

bandwidth utilization indications

• 3.46 x 17.5 x 12 in. (8.8 x 44.5 x 30.5 cm)

• 13.5 lb (6.12 kg)

• 15 lb (6.8 kg) with two modules installed
