SSH Secure Shell (SSH) is a protocol that provides a secure, remote connection to a device. SSH version 2 is currently supported. The SSH server feature enables an SSH client to establish a secure, encrypted connection with a device. This connection provides functionality that is similar to an inbound telnet connection. SSH uses RSA and DSA Public Key cryptography for device connections and authentication. TACACS+ TACACS+ provides centralized security for validation of users accessing the device. TACACS+ provides a centralized user management system, while still retaining consistency with RADIUS and other authentication processes. For more information, see "Defining TACACS+ Settings." Password Management Password management provides increased network security and improved password control. Passwords for SSH, Telnet, HTTP, HTTPS, and SNMP access are assigned security features. For more information on Password Management, see "Managing Passwords". Access Control Lists (ACL) Access Control Lists (ACL) allow network managers to define classification actions and rules for specific ingress ports. Packets entering an ingress port, with an active ACL, are either admitted or denied entry and the ingress port is disabled. If they are denied entry, the user can disable the port. For more information, see "ACL Overview" on page 276. DHCP Snooping DHCP Snooping expands network security by providing firewall security between untrusted interfaces and DHCP servers. By enabling DHCP Snooping network administrators can differentiate between trusted interfaces connected to end-users or DHCP Servers and untrusted interfaces located beyond the network firewall. For more information, see "Configuring DHCP Snooping" on page 288. Additional CLI Documentation The CLI Reference Guide, which is available on the Documentation CD, provides information about the CLI commands used to configure the device. The document provides information about the command description, syntax, default values, guidelines, and examples. 26 Introduction
