If a port needs to be part of multiple VLANs, the IF
definition must be repeated for corresponding VLAN IDs as:
"IF3": { "GWV4": "<IP_Address>", "DHCP": "<Dhcp_flag>", "Port": "Pkt1", "VlanId": "<VLAN_ID_1>", "IPV4": "<IP_Address/Subnet_Prefix>" }, "IF4": { "GWV4": "<IP_Address>", "DHCP": "<Dhcp_flag>", "Port": "Pkt1", "VlanId": "<VLAN_ID_2>", "IPV4": "<IP_Address/Subnet_Prefix>" }, "IF5": { "GWV4": "<IP_Address>", "DHCP": "<Dhcp_flag>", "Port": "Pkt1", "VlanId": "<VLAN_ID_3>", "IPV4": "<IP_Address/Subnet_Prefix>" }

IF
dictionary name is any name prefixed by IF
.Example : IF-ABC
, IFASD, IF_AS,
and so on.
The name for alternate IP address on a port can be constructed with port/vlan information.
Example: The second alternate IP address for pkt0's first VLAN IP interface can be named as PKT0_V01_ALT_IP_02.
The maximum length of the name is 255 characters.
This section describes about the individual parameters of the metadata passed to the server:
"IF3": { "Port": "Pkt0", "DHCP": "False", "GWV4": "10.0.3.1", "IPV4": "10.0.3.187/24", "GWV6": "fd00:10:6b50:4350::6", "IPV6": "fd00:10:6b50:4350::69/64", "FIPV4": "54.32.21.12", "RNat": "true", "VlanId":"222" }
The elements which constitutes an interface definition:
Parameters | Description |
---|---|
IFX | Interface definition name This element is the name of the dictionary which contains the information of the port. Here, "IF" is a key word, and it can be appended with any name/identifier. Example: IF_Pkt0, IFMgt0, IF-MediaPort. Note: The name provided for Interface definition is used in Alternate IP definition. A link is formed between the two definitions based on the Interface definition name. |
DHCP | This flag is used to enable or disable the DHCP. If the DHCP is set to False, you need to provide fixed IP for each ports. |
Port | Port Name One of – Mgt0, Ha0, Pkt0, Pkt1. This indicates the actual port to which the definition belongs to. |
IPV4 | Primary IP on the Private Port + Prefix - v4 Should be provided only in case of DHCP disabled on the port requires V4 address. Example: 10.54.116.53/23 |
GWV4 | Gateway IP v4 Should be provided only in case of DHCP disabled on the port requires V4 address. Note : GWV4 and IPV4 are interdependent, both have to be provided in noDHCP V4 scenario. |
IPV6 | IP on the Private Port + Prefix - v6 Should be provided only in case of DHCP disabled on the port requires v6 address. Example : fd00:10:6b50:4350::69/64 |
GWV6 | Gateway IP v6 Should be provided only in case of DHCP disabled on the port requires v6 address. Note : GWV6 and IPV6 are interdependent, both have to be provided in noDHCP v6 scenario. |
FIPV4 | Floating IP associated on the Port. Provide when the Floating IP is associated (in DHCP enabled and disabled scenario) with the port. |
RNat | Reverse NAT flag Values:
Default value - True |
VlanId | ID of the port VLAN. |
Alternate IP definition contains the information of an additional IP addresses associated with the port. For each additional IP address added to the port, there has to be corresponding ALT IP definition. The maximum number of ALT IP (alternate IP address) that can be associated with a port is restricted to 14.
"AltIP3" : { "IFName":"IF2", "IP": "10.2.0.7", "FIPV4":"aaa.bbb.ccc.eee" }
Parameter | Description |
---|---|
AltIP3 | Alternate IP (ALT IP) definition name/identifier. Alternate IP address associated with a port. This identifier does not have any restriction on naming. Example for ALT IP identifier : Alt_Pkt0_AX, ALT_PKT0_01, signaling_Pkt0_05. |
IFName | Interface definition Name Indicates the association between the ALT IP address and the interface definition. When the user changes the interface definition name (i.e IFX name), the user must simultaneously change the IFName value in this definition. Otherwise, the link between ALT IP and it's port is lost. |
IP | IPV4 or IPV6 address IP address that needs to be associated with the port. User can type v4 or v6 address, based on what version the parent interface dictionary contains. When IF definition has v4/v6 address, the ALT IP definition also must have only v4/v6 address. In case of dual-stack scenario, since, Interface dictionary has both V4 and V6 addresses, the ALT IP definition can also have v4 and v6 addresses. But both have to be defined in separate ALT dictionary, pointing to it's parent dictionary. |
FIPV4 | Floating IP on the Alternate IP If a floating IP is associated with the ALT (alternate/additional) IP, the value against this field must contain the floating IP. Note: The RNat flag which is defined in interface dictionary is an interface-wide entity. If the RNat flag is disabled in interface dictionary, the FIP value provided in the ALT IP definition is not considered while populating the metaVariables for this port. |
The parameter ClusterIp
is used for Redundancy Group (RG) formation during startup. You must pass HA0
IP of one of the nodes of RG as ClusterIp parameter.
ClusterIp: "<RG_IP>"
Parameter | Description |
---|---|
ClusterIp | ClusterIP is used for Redundancy Group (RG) formation on startup. |

Interface related information (contents of Interface and ALT IP definition) provided in userdata and/or metadata is flattened down into key-value pairs, which is used for CLI configuration.
