Overview
Using ExtremeWare XOS, you can manage the switch using the following methods:
●
Access the command line interface (CLI) by connecting a terminal (or workstation with terminal-
emulation software) to the console port.
●
Access the switch remotely using TCP/IP through one of the switch ports or through the dedicated
10/100 unshielded twisted pair (UTP) Ethernet management port. Remote access includes:
■
Telnet using the CLI interface.
■
Secure Shell (SSH2) using the CLI interface.
■
Simple Network Management Protocol (SNMP) access using EPICenter or another SNMP
manager.
●
Download software updates and upgrades. For more information, see Appendix A , “ Software
Upgrade and Boot Options .”
The switch supports up to the following number of concurrent user sessions:
●
One console session
■
Two console sessions are available if two management modules are installed.
●
Eight shell sessions
●
Eight Telnet sessions
●
Eight Trivial File Transfer Protocol (TFTP) sessions
