Benefit
• Archive download is a convenient tool to upgrade (or downgrade) the set of binaries
on the switch. It performs memory availability checks and automatically configures the
switch to use the new binaries. Archive upload can be used to archive the existing set
of binaries on the switch to a storage (such as a TFTP server).
• Auto-configuration eases deployment of switches in the network by automatically
configuring multiple switches across a network via a boot server.
• Auto-negotiating on all ports automatically selects half- or full-duplex transmission
mode to optimize bandwidth.
• Cisco VTP supports dynamic VLANs and dynamic trunk configuration across all
switches.
• Voice VLAN simplifies telephony installations by keeping voice traffic on a separate
VLAN for easier network administration and troubleshooting.
• Dynamic Trunking Protocol (DTP) enables dynamic trunk configuration across all ports
in the switch.
• Port Aggregation Protocol (PAgP) automates the creation of Cisco Fast EtherChannel
or Gigabit EtherChannel groups, enabling linking to another switch, router, or server.
• IEEE 802.3z-compliant 1000BASE-SX and 1000BASE-LX physical interface support
through a field-replaceable SFP module provides customers unprecedented flexibility
in switch deployment.
• The default configuration stored in Flash ensures that the switch can be quickly
connected to the network and can pass traffic with minimal user intervention.
• The switches support non-standard Ethernet frame sizes up to 1,536 bytes.
