External ports
Up to ten 10 Gb SFP+ ports (also designed to support 1 Gb SFP if required, flexibility of
mixing 1 Gb/10 Gb)
One 10/100/1000 Mb copper RJ-45 used for management
An RS-232 mini-USB connector for serial port that provides an additional means to install
software and configure the switch module
Scalability and performance
Stacking support up to 8 switches
Autosensing 1 Gb/10 Gb internal and external Ethernet ports for bandwidth optimization
Non-blocking architecture with wire-speed forwarding of traffic and full line rate performance
of 480 Gbps full duplex
Media access control (MAC) address learning: automatic update, supports up to 32 Kb MAC
addresses
Up to 128 IP interfaces per switch
Static, EtherChannel, and LACP (IEEE 802.3ad) link aggregation, up to 100 Gb of total
bandwidth per switch, up to 18 trunk groups, and up to eight ports per group
Support for jumbo frames (up to 9,216 bytes)
Broadcast/multicast storm control
IGMP snooping for limit flooding of IP multicast traffic (IGMP V1, V2, and V3)
Configurable traffic distribution schemes over trunk links based on source/destination IP
addresses, MAC addresses, or both
Fast port forwarding and fast uplink convergence for rapid STP convergence
Availability and redundancy
VRRP for Layer 3 router redundancy
IEEE 802.1D STP for providing Layer 2 redundancy with PVRST+
IEEE 802.1s Multiple STP (MSTP) for topology optimization, up to 128 STP instances
supported by single switch

on blades
Interchassis redundancy (Layer 2 and Layer 3)
VLAN support
Up to 1024 VLANs supported per switch; VLAN numbers ranging from 1 to 4095 (4095 is
used for the management module's connection only.)
802.1Q VLAN tagging support on all ports
Ingress VLAN tagging support to tunnel packets through a public domain without altering the
original 802.1Q

VLAN-based, MAC-based, and IP-based access control lists (ACLs)
802.1X port-based authentication
Multiple user IDs and passwords
User access control
Radius, TACACS+, LDAP authentication and authorization
NIST 800-131A Encryption
Quality of service (QoS)
Support for IEEE 802.1p, IP ToS/DSCP, and ACL-based (MAC/IP source and destination
addresses, VLANs) traffic classification and processing
Traffic shaping and re-marking based on defined policies
Up to eight weighted round robin (WRR) priority queues per port for processing qualified
traffic
IPv4/IPv6 ACL metering
