Boot Config Field Descriptions
Use the data in the following table to use the Boot Config tab.
Name |
Description |
---|---|
SwVersion |
Specifies the software version that currently runs on the switch. |
LastRuntimeConfigSource |
Specifies the last source for the run-time image. |
PrimaryConfigSource |
Specifies the primary configuration source. |
PrimaryBackupConfigSource |
Specifies the backup configuration source to use if the primary does not exist. |
EnableFactoryDefaultsMode |
Specifies whether the switch uses the factory default settings after you reboot the switch. The options are:
The default value is false. This flag is automatically reset to the default value after the switch restarts. If you select an option but then want to select a different option and have not yet rebooted the switch, you must disable the first option before you select the second option. |
EnableDebugMode |
Enabling the debugmode allows a user to enable TRACE on any port by prompting the selection on the console during boot up. This allows the user start trace for debugging earlier on specified port. It only works on console connection. The default value is disabled. Important:
Do not change this parameter. |
EnableRebootOnError |
Activates or disables automatic reboot on a fatal error. The default value is activated. Important:
Do not change this parameter. |
EnableTelnetServer |
Activates or disables the Telnet server service. The default value is disabled. |
EnableFtpServer |
Activates or disables the FTP server on the switch. The default value is disabled. To enable FTP, ensure that the TFTPD flag is disabled. |
EnableTftpServer |
Activates or disables Trivial File Transfer Protocol server service. The default value is disabled. |
EnableSshServer |
Activates or disables the SSH server service. The default value is disabled. |
EnableSpbmConfigMode |
Enables you to configure SPB and IS-IS, but you cannot configure PIM and IGMP either globally or on an interface. The boot flag is enabled by default. |
EnableIpv6Mode |
Enable this flag to support IPv6 routes with prefix-lengths greater than 64 bits. This flag is disabled by default. |
EnableEnhancedsecureMode |
Enables or disables the enhanced secure mode. Select either jitc or non-jitc to enable the enhanced secure mode in one of these sub-modes. The default is disabled. Note:
As a best practice, enable the enhanced secure mode in the non-JITC sub-mode because the JITC sub-mode is more restrictive and prevents the use of some troubleshooting utilities. |
EnableUrpfMode |
Enables Unicast Reverse Path Forwarding (uRPF) globally. You must enable uRPF globally before you configure it on a port or VLAN. The default is disabled. |
EnableVxlanGwFullInterworkingMode Note:
Exception: only supported on 7520 Series and 7720 Series. |
Enables VXLAN Gateway in Full Interworking Mode, which supports SPB, SMLT, and vIST. By default, the Base Interworking Mode is enabled and Full Interworking Mode is disabled. You change modes by enabling this boot configuration flag. In Base Interworking Mode, VXLAN Gateway supports Layer 2 gateway communication between VXLAN and traditional VLAN environments. |
EnableFlowControlMode |
Enables or disables flow control globally. When disabled, the system does not generate nor configure the transmission of flow control messages. The system always honors received flow control messages regardless of the flow control mode status. You must enable this mode before you configure an interface to send pause frames. The default is disabled. |
AdvancedFeatureBwReservation Note:
Exception: high is supported on 5720 Series, 7520 Series, and 7720 Series . Exception: low is not supported on 5720 Series. Exception: vim is only supported on 5520 Series and 5720 Series. |
Enables the switch to support advanced features by reserving ports as loopback ports. When disabled, you can use all ports on the switch, but advanced features do not work. When you select low or high, the corresponding bandwidth of the reserved Ethernet ports is allocated to the loopback required for advanced feature functionality. When you select vim, the bandwidth is allocated from the unused vim slot capacity and cannot be selected if the VIM card is present. The default varies depending on the platform:
If you change this parameter, you must restart the switch. |
EnableDvrLeafMode |
Enables the switch to be configured as a DvR Leaf. When enabled, you cannot configure the switch to operate as a DvR Controller. |
EnablevrfScaling |
Changes the maximum number of VRFs and Layer 3 VSNs that the switch supports. If you select this check box, the maximum number increases. The default is disabled. Important:
If you select both this check box and the EnableSpbmConfigMode check box, the switch reduces the number of configurable VLANs. For more information about maximum scaling numbers, see Fabric Engine Release Notes. |
EnableSyslogRfc5424Format |
Enables or disables the RFC 5424 syslog format. The default is enabled. If the pre-existing configuration file is for a release prior to this enhancement, then the flag is disabled automatically. |
NniMstp |
Enables MSTP, and allows non SPBM B-VLAN configuration on SPBM network-to-network interface (NNI) ports. The default is disabled. Note:
Spanning Tree is disabled on all SPBM NNIs. You cannot add an SPBM NNI port or MLT port to any non SPBM B-VLAN. |
EnableIpv6EgressFilterMode |
Enables IPv6 egress filters. The default is disabled. If you change this parameter, you must restart the switch. For 5320 Series, 5420 Series, and 5720 Series platforms, EnableIpv6EgressFilterMode and EnableMacsec are mutually exclusive. |
EnableMacsec Note:
Exception: only required for 5320 Series and 5420 Series. |
Enables Media Access Control Security (MACsec) mode globally. To enable MACsec mode, you must configure the boot flag. EnableIpv6EgressFilterMode and EnableMacsec are mutually exclusive. |
EnableSpbmNodeScaling Note:
Exception: only applies to 5320 Series and 5420 Series. |
Enables the switch to increase the number of supported SPB nodes per area. By default, the switch supports up to 350 SPB nodes per area. The default is disabled. If you change this parameter, you must restart the switch. |
Slot |
Specifies the slot number. |
TftpHash |
Enables TFTP hashing. |
TftpRetransmit |
Set TFTP retransmit timeout counter. |
TftpTimeout |
Set TFTP timeout counter. |
User |
Configure host user. |
Password |
Configure host password. |
