Enable IPv6 Egress Filters
Enable IPv6 egress filters to add IPv6 egress qualifiers at startup.
About this task
This flag is disabled by default.
Before you begin
If more than 200 IPv4 egress entries exist in the configuration file, make a backup of the configuration file before you enable IPv6 egress filters. Only a maximum of 200 IPv4 egress entries are saved in the configuration file after you save the configuration.
For example, you can enter more than 200 IPv4 egress entries in the configuration file prior to enabling IPv6 egress filters. However, the entries are stored in ascending numerical order with ACL ID and ACE ID respectively, and not in the order in which they were added. Therefore, after you enable IPv6 egress filters and restart, and because the configuration file is read in ascending order, you receive an error message after the 200 maximum has been reached, such as:
CP1 [2017-09-28T00:44:24.077+05:30] 7K-Fi-94-I6:1 0x001049d4 00000000 GlobalRouter FILTER ERROR Unable to allocate data path resources for ACL ID 12.

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 chassis. |
|
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 at startup.
The default value is false. This flag is automatically reset to the default setting after the switch restarts. If you change this parameter, you must restart the switch for the change to take effect. |
|
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. |
|
EnableRloginServer Note:
Exception: only supported on VSP 8600 Series. |
Activates or disables the rlogin and rsh server. 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 Note:
Exception: not supported on VSP 4450 Series or XA1400 Series . |
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 VSP 7200 Series, VSP 7400 Series, VSP 8200 Series, and VSP 8400 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 Note:
Exception: not supported on VSP 8600 Series. |
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: only supported on 5520 Series, VSP 7400 Series and XA1480. |
Enables the switch to support advanced features. The default is enabled with low level configuration. The high level means that the switch reserves the maximum bandwidth for the advanced features. The low level means that the switch reserves less bandwidth to support minimum functionality for advanced features. 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 Release Notes for VOSS. |
|
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 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. |
|

Specifies the slot number, either 1 or 2, for the master CPU. The default value is 1. |
|
EnableHaCpu Note:
Exception: only supported on VSP 8600 Series. |

|
EnableSavetoStandby Note:
Exception: only supported on VSP 8600 Series. |
Enables or disables automatic save of the configuration file to the standby CPU. The default value is enabled. |
