- Up to two simultaneous encrypted SSH (Secure Shell) connections for multiple
CLI-based sessions over the network. Refer to
Establishing an SSH Connection
page 66 for further information.
- SNMP (Simple Network Management Protocol) "get" and "set" requests (support for
SNMPv1, SNMPv2 and SNMPv3). Refer to
on page 73 for further
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
Establishing a Modem (PPP) Connection
for further information.
●
Allowed managers to restrict access to a pre-defined list of IP addresses. Refer to
on page 84 for further information.
●
Software upgrades by TFTP. Refer to
information.
●
Configuration upload/download by TFTP and SCP. Refer to
Device Configurations and Images
on page 99 for further information.
●
"Allowed protocols" allows you to selectively enable and disable the IP protocols. Refer to
on page 86 for further information.
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
on page 127 for further information.
- 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
on page 137 for further information.
●
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.
