- Up to two simultaneous encrypted SSH (Secure Shell) connections for multiple
CLI-based sessions over the network. Refer to
page 66 for further information.
- SNMP (Simple Network Management Protocol) "get" and "set" requests (support for
SNMPv1, SNMPv2 and SNMPv3). Refer to
information.
Out-of-band management access through the switch console port to a directly attached
terminal or remote terminal via a serial connection or modem. Refer to
Console Connection
for further information.
Allowed managers to restrict access to a pre-defined list of IP addresses. Refer to
Managers
Software upgrades by TFTP. Refer to
information.
Configuration upload/download by TFTP and SCP. Refer to
Device Configurations and Images
"Allowed protocols" allows you to selectively enable and disable the IP protocols. Refer to
Allowed Protocols

Redundancy

IEEE 802.1w Rapid Spanning Tree Protocol (RSTP) for rapid convergence of the spanning
tree by immediately transitioning root and designated ports to the forwarding state.
- RSTP automatically detects switches that are configured as 802.1w Rapid Spanning
Tree or 802.1D Spanning Tree and operates accordingly. Refer to
Protocol
- Edge port for eliminating the forwarding delay by enabling a port to immediately transition
from the blocking state to the forwarding state.
Port redundancy provides a backup for important links. If one link fails, the backup link
takes over, preventing disruption to network traffic. Refer to
for further information.
Inter-module redundancy is hardware-based and intended for important links that need to
be maintained even if there are changes in the stack. Refer to
Redundancy
Port redundancy combined with 802.1w provides configuration flexibility in complex
network configurations.
LAG redundancy adds the reliability of port redundancy to LAGs, thus providing inter-port
as well as intra-port redundancy.
