•
Network Time Protocol (NTP) for providing a consistent time stamp to all switches from an external
source
•
Cisco IOS File System (IFS) for providing a single interface to all file systems that the switch uses
•
Configuration logging to log and to view changes to the switch configuration
•
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
