Cisco Catalyst Blade Switch 3020 for HP Software Configuration Guide
1-2
Express Setup for quickly configuring a switch for the first time with basic IP information, contact
information, switch and Telnet passwords, and Simple Network Management Protocol (SNMP)
information through a browser-based program. For more information about Express Setup, see the
getting started guide.
An embedded device manager GUI for configuring and monitoring a single switch through a web
browser. For information about launching the device manager, see the getting started guide. For more
information about the device manager, see the switch online help.
Autosensing of port speed and autonegotiation of duplex mode on all switch ports for optimizing
bandwidth
Automatic-medium-dependent interface crossover (auto-MDIX) capability on 10/100/1000 Mbps
interfaces that enables the interface to automatically detect the required cable connection type
(straight-through or crossover) and to configure the connection appropriately
Support for up to 9000 bytes for frames that are bridged in hardware and up to 2000 bytes for frames
that are bridged by software
IEEE 802.3x flow control on all ports (the switch does not send pause frames)
EtherChannel for enhanced fault tolerance and for providing up to 8 Gbps (Gigabit EtherChannel)
full-duplex bandwidth among switches, routers, and servers
Port Aggregation Protocol (PAgP) and Link Aggregation Control Protocol (LACP) for automatic
creation of EtherChannel links
Forwarding of Layer 2 packets at Gigabit line rate
Per-port storm control for preventing broadcast, multicast, and unicast storms
Port blocking on forwarding unknown Layer 2 unknown unicast, multicast, and bridged broadcast
traffic
Internet Group Management Protocol (IGMP) snooping for IGMP Versions 1, 2, and 3 for
efficiently forwarding multimedia and multicast traffic
IGMP report suppression for sending only one IGMP report per multicast router query to the
multicast devices (supported only for IGMPv1 or IGMPv2 queries)
IGMP snooping querier support to configure switch to generate periodic IGMP General Query
messages
Multicast VLAN registration (MVR) to continuously send multicast streams in a multicast VLAN
while isolating the streams from subscriber VLANs for bandwidth and security reasons
IGMP filtering for controlling the set of multicast groups to which hosts on a switch port can belong
IGMP throttling for configuring the action when the maximum number of entries is in the IGMP
forwarding table
IGMP leave timer for configuring the leave latency for the network
