Catalyst 2360 Switch Software Configuration Guide
1-4
Unique device identifier to provide product identification information through a show inventory
user EXEC command display
In-band management access through the device manager over a Netscape Navigator or Microsoft
Internet Explorer browser session
In-band management access for up to 16 simultaneous Telnet connections for multiple CLI-based
sessions over the network
In-band management access for up to five simultaneous, encrypted Secure Shell (SSH) connections
for multiple CLI-based sessions over the network (requires the cryptographic software image)
In-band management access through SNMP Versions 1, 2c, and 3 get and set requests
Out-of-band management access through the switch console port to a directly attached terminal or
to a remote terminal through a serial connection or a modem
Out-of-band management access through the Ethernet management port to a PC
Secure Copy Protocol (SCP) feature to provide a secure and authenticated method for copying
switch configuration or switch image files (requires the cryptographic software image)
The HTTP client in Cisco IOS sends requests to both IPv4 and IPv6 HTTP servers, and the HTTP
server in Cisco IOS services HTTP requests from both IPv4 and IPv6 HTTP clients
IPv6 supports stateless autoconfiguration to manage link, subnet, and site addressing changes, such
as management of host and mobile IP addresses.
DHCP server port-based address allocation for the preassignment of an IP address to a switch port.
Wired location service sends location and attachment tracking information for connected devices to
a Cisco Mobility Services Engine (MSE).
CPU threshold trap monitors CPU use.
Support for including a hostname in the option 12 field of DHCPDISCOVER packets. This provides
identical configuration files to be sent by using the DHCP protocol.
DHCP Snooping enhancement to support the selection of a fixed string-based format for the
circuit-id sub-option of the Option 82 DHCP field.
USB mini-Type B console port in addition to the RJ-45 console port. Console input is active on only
one port at a time.
USB Type A port for external Cisco USB flash memory devices (thumb drives or USB keys). You
can use Cisco CLI commands to read, write, erase, copy, or boot from the flash memory.
UniDirectional Link Detection (UDLD) and aggressive UDLD for detecting and disabling
unidirectional links on fiber-optic interfaces caused by incorrect fiber-optic wiring or port faults
802.1D Spanning Tree Protocol (STP) for redundant backbone connections and loop-free networks.
STP has these features:
– Up to 128 supported spanning-tree instances
Per-VLAN spanning-tree plus (PVST+) for load-balancing across VLANs
–
– Rapid PVST+ for load-balancing across VLANs and for rapid convergence of spanning-tree
instances
– UplinkFast and BackboneFast for fast convergence after a spanning-tree topology change and
to achieve load-balancing between redundant uplinks, including Gigabit uplinks
