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.

Procedure

In the navigation pane, expand the Configuration > Edit folders.
Click Chassis.
Click the Boot Config tab.
Select the EnableIpv6EgressFilterMode check box.
Click Apply.
Save the configuration, and then restart the switch for the change to take effect.

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: false: The node does not use factory default settings. fabric: This mode is not supported. noFabric: The node uses the factory default mode settings. Removes the configuration files, primary and secondary config file names, all user account passwords, digital certificates, IKE/OSPF/IS-IS keys, and SNMP communities. All ports are disabled and assigned to VLAN 1. License files are not removed. config-only Boots the switch with a blank configuration. This parameter preserves configuration files, primary and secondary configuration file names, user accounts and passwords, digital certificates, IKE/OSPF/IS-IS keys, license files, and SNMP communities. All ports are disabled and assigned to VLAN 1. Use this parameter as a temporary troubleshooting option to test or investigate if something is wrong with the configuration without permanently removing the configuration files, user accounts, and other preserved items. reset-all-files: Equivalent to a switch that ships from the factory. The switch has no configuration files, default user accounts, default security mode, Auto-sense-enabled ports, removes license files, and performs a ZTP+ configuration after reboot. The 30-day factory license is also reset. Important: Only CLI provides two options to achieve the same behavior; there is no option other than reset-all-files in EDM. zero-touch: Boots the switch with a default configuration that enables Auto-sense. This parameter resets secure files but keeps the security mode and performs a ZTP+ configuration after reboot. License files are not removed. 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. Note: Exception: config-only, reset-all-files, and zero-touch do not apply to VSP 4450 Series, XA1400 Series, and VSP 8600 Series.
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 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 VSP 7400 Series and XA1480.	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. The default is enabled with low level. 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 VOSS 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.
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.
