vsf member reboot
Syntax
boot vsf member <MEMBER-ID>
Description
Reboot the VSF member and have it rejoin the virtual chassis with the current configuration. If the boot option is
specified, the switch will come back up with the existing member-ID and rejoin the virtual chassis with the current
configuration.
Parameters
<MEMBER-ID>
The VSF member-ID for the member command or parameter. Member ID value can be in the range of 1 to 8.
Restriction
Reboot will not be available until VSF is enabled.
vsf member remove
This command removes the entire configuration for a specified member. After issuing the command, the specified
member-ID is available for reuse and may be provisioned or assigned to another device.
If the member physically exists, its configuration will be erased. It will then be powered down by default.
Syntax
vsf member <MEMBER-ID> remove
Description
Erase the VSF virtual chassis member configuration.
Parameters
<MEMBER-ID>
The VSF member-ID for the member command/ or parameter. Member ID value can be in the range of 1 to 8.
Restriction
Remove will not be available until VSF is enabled.
vsf member remove reboot
Syntax
vsf member <MEMBER-ID> remove reboot
Description
Removes the entire configuration for a specified member and reboots it. If the member physically exists, its
configuration will be erased. If the VSF link is still present, the member reboots and joins the stack through
automatic configuration.
Command context
config
Parameters
<MEMBER-ID>
The VSF member-ID for the member command/ or parameter. Member ID value can be in the range of 1 to 8.

Summary

Time Protocols

General steps for running a time protocol on the switch

Ensures uniform time among interoperating devices for management and troubleshooting by attaching meaningful time data to event and error messages.

SNTP time synchronization

SNTP provides three operating modes: Broadcast mode, DHCP mode, and Unicast mode.

NTP time synchronization

Synchronizes time of day among distributed time servers and clients to correlate events from multiple network devices.

SNTP client authentication

Validates SNTP messages received from NTP or SNTP servers before updating network time, requiring matching authentication keys.

Port Status and Configuration

Viewing port status and configuring port parameters

Guides on checking port mode settings and displaying transceiver information for fixed-configuration devices.

Enabling or disabling ports and configuring port mode (CLI)

Allows configuration of port parameters such as speed-duplex and auto-MDIX.

Uni-directional link detection (UDLD)

Monitors link between switches, blocking ports on both ends if link fails, particularly useful for fiber links and trunks.

Uplink Failure Detection

Monitors link state of ports configured as links-to-monitor (LtM) and disables links-to-disable (LtD) ports upon link loss.

Power Over Ethernet (PoE/PoE+) Operation

PoE operation

Enables/disables PoE, monitors status, configures power thresholds, and specifies port priority for power allocation.

Configuring the PoE port priority

Reconfigures PoE priority levels on ports, prioritizing by port number in ascending order.

PoE/PoE+ allocation using LLDP information

Allows automatic power configuration based on link partner's capabilities via LLDP.

Port Trunking

Trunk configuration methods

Covers dynamic LACP trunks and static trunks, including using keys to control dynamic LACP configuration.

Dynamic LACP trunk

Automatically negotiates trunked links between LACP-configured ports, supporting Active or Passive LACP.

Static trunk

Manually configured static trunks using the Port/Trunk Settings screen or the trunk command.

Port Traffic Controls

Rate-limiting

Operates on a per-port basis to limit bandwidth for inbound or outbound traffic, dropping traffic exceeding the limit.

ICMP rate-limiting

Restricts ICMP traffic to percentage levels to throttle worms or viruses, preserving inbound bandwidth for non-ICMP traffic.

Jumbo frames

Configures maximum transmission unit (MTU) for jumbo frames, allowing inbound frames up to 9220 bytes.

Fault Finder

Helps debug unusual network activity like flapping links or transceivers, or troubleshoot multicast/broadcast storms.

Configuring for Network Management Applications

Using SNMP tools to manage the switch

SNMP client application retrieves device configuration and status, and configures the switch.

SNMPv3 access to the switch

Requires IP address configuration and covers enabling SNMPv3, configuring users, communities, and traps.

LLDP

Standard-based method for switches to advertise themselves to adjacent devices and learn about them.

DHCPv4 server

DHCPv4 configuration commands

Commands for configuring the DHCPv4 server, including pools, options, boot file, default router, and DNS servers.

DHCPv6 server

DHCPv6 snooping and relay

Configures DHCPv6 snooping and Dynamic IPv6 Lockdown (DIPLDv6) through SNMP.

ipv6 source-binding

Adds a DHCPv6 static binding entry into the binding table with infinite lifetime.

Zero Touch Provisioning with AirWave and Central

ZTP with AirWave

Supports ZTP using DHCP servers for on-premise management or Activate for cloud-based management.

DHCP-based ZTP with AirWave

Configures switches for ZTP using DHCP option 43 or 60 for AirWave details.
