4.6 EDGE / DEPARTMENT/ BUILDING SWITCH
Physical Specification:
Should be rack mountable with 20-port 10/100/1000Mbps and 4 1000BaseT or SFP slots
General Specification:
Switch with 32 Gbps Switching Fabric
35.7 million packets per second forwarding rate on 64-byte packets
8000 MAC address supported
255 IGMP groups
Should support Redundant Power Supply
Layer-2 Features
IEEE 802.1Q VLAN encapsulation. Up to 255 VLANs per switch and upto 4000 VLAN IDs
Support for Automatic Negotiation of Trunking Protocol, to help minimize the configuration & errors
Centralized VLAN Management. VLANs created on the Core Switches should be propagated to all
the other switches automatically, thus reducing the overhead of creating / modifying / deleting VLANs
in all the switches in turn eliminating the configuration err
Spanning-tree PortFast for fast convergence
802.1d, 802.1p, 802.1Q, 802.1s, 802.1w, 802.1x, 802.1ab, 802.3ad,
Spanning-tree root guard to prevent other edge switches becoming the root bridge.
IGMP snooping v1, v2 and v3
Link Aggregation Protocol (LACP)
Support for Detection of Unidirectional Links and to disable them to avoid problems such as
spanning-tree loops
Should be able to discover the neighboring device of the same vendor giving the details about the
platform, IP Address, Link connected through etc, thus helping in troubleshooting connectivity
problems.
Support for Switch port auto recovery (err disable) to automatically re-enable a link that is disabled
because of a network error.
Should support Multicast VLAN registration
Should support DHCP Server enabling a convenient deployment option for the assignment of IP
addresses in networks that do not have without a dedicated DHCP server
Should support Local Proxy Address Resolution Protocol (ARP) works in conjunction with Private
VLAN Edge to minimize broadcasts and maximize available bandwidth
Should support LLDP and LLDP-MED including client location information. Should exchange link
and device information in multivendor networks.
Should support configuration rollback to replace current configuration with any saved configuration
file. Should support link state tracking which provides layer2 redundancy in the network when used
in conjunction with server teaming.
Support Configurable maximum transmission unit (MTU) of up to 9000 bytes, with a maximum
Ethernet frame size of 9018 bytes (Jumbo frames) for bridging on Gigabit Ethernet ports
Support Autosensing speed on 10/100 ports, Autonegotiating half/full-duplex on all ports and Auto-
MDIX
QoS Features
Per-port broadcast, multicast, and unicast storm control
Standard 802.1p CoS and DSCP classification using marking and reclassification on a per-packet
basis by source and destination IP address, source and destination MAC address, or Layer 4 TCP or
UDP port number.
