Summary/usage

map add rule index <domain> psid <psid> ip6-dst <ip6-addr>.

Description

Add MAP rule to a domain

Example usage

vpp# map add rule

Declaration and implementation

Declaration: map_add_rule_command (src/plugins/map/map.c line 2144)

Implementation: map_add_rule_command_fn.

map del domain

Summary/usage

map del domain index <domain>.

Description

Delete MAP domain

Example usage

vpp# map del domain

Declaration and implementation

Declaration: map_del_command (src/plugins/map/map.c line 2157)

Implementation: map_del_domain_command_fn.

map interface

Summary/usage

map interface <interface-name> [map-t] [del].

Description

Enable MAP processing on interface (input feature)

Declaration and implementation

Declaration: map_if_command (src/plugins/map/map.c line 2206)

Implementation: map_if_command_fn.

map params fragment

Summary/usage

map params fragment inner|outer ignore-df|honor-df.

Description

Configure MAP fragmentation behaviour

Example usage

vpp# map params fragment

Allows fragmentation of the IPv4 packet even if the DF bit is set. The choice between inner or outer fragmentation of tunnel packets is complicated. The benefit of inner fragmentation is that the ultimate endpoint must reassemble, instead of the tunnel endpoint.

Declaration and implementation

Declaration: map_fragment_command (src/plugins/map/map.c line 2114)

Implementation: map_fragment_command_fn.

map params icmp source-address

Summary/usage

map params icmp source-address <ip4-address>.

Description

Specifiy the IPv4 source address used for relayed ICMP error messages

Example usage
vpp# map params icmp source-address

This command specifies which IPv4 source address (must be local to the system), that is used for relayed received IPv6 ICMP error messages.

Declaration and implementation

Declaration: map_icmp_relay_source_address_command (src/plugins/map/map.c line 2079)

Implementation: map_icmp_relay_source_address_command_fn.

map params icmp6 unreachables

Summary/usage

map params icmp6 unreachables {on|off}.

Description

Send IPv6 ICMP unreachables

Example usage
vpp# map params icmp6 unreachables

Send IPv6 ICMP unreachable messages back if security check fails or no MAP domain exists.

Declaration and implementation

Declaration: map_icmp_unreachables_command (src/plugins/map/map.c line 2095)

Implementation: map_icmp_unreachables_command_fn.

map params pre-resolve

Summary/usage

 map params pre-resolve {ip4-nh <address>} | {ip6-nh <address>}.

Description

Bypass IP4/IP6 lookup

Example usage
vpp# map params pre-resolve

Bypass a second FIB lookup of the translated or encapsulated packet, and forward the packet directly to the specified next-hop. This optimization trades forwarding flexibility for performance.

Declaration and implementation

Declaration: map_pre_resolve_command (src/plugins/map/map.c line 2037)

Implementation: map_pre_resolve_command_fn.

map params reassembly

Summary/usage

map params reassembly [ip4 | ip6] [lifetime <lifetime-ms>] [pool-size <pool-size>] [buffers <buffers>] [ht-ratio <ht-ratio>].

Description

Configure MAP reassembly behaviour

Example usage
vpp# map params reassembly

Declaration and implementation

Declaration: map_ip4_reass_lifetime_command (src/plugins/map/map.c line 1983)

Implementation: map_params_reass_command_fn.

map params security-check

Summary/usage

map params security-check enable|disable fragments on|off.

Description

Enable or disable the MAP-E inbound security check
Specifiy if the inbound security check should be done on fragments

Example usage
vpp# map params security-check

By default, a decapsulated packet's IPv4 source address will be verified against the outer header's IPv6 source address. Disabling this feature will allow IPv4 source address spoofing.

Typically the inbound on-decapsulation security check is only done
on the first packet. The packet that contains the L4
information. While a security check on every fragment is possible,
it has a cost. State must be created on the first fragment.

Declaration and implementation

Declaration: map_security_check_command (src/plugins/map/map.c line 2061)

Implementation: map_security_check_command_fn.

map params tcp-mss

Summary/usage

map params tcp-mss <value>.

Description

TCP MSS clamping

Example usage
vpp# map params tcp-mss

This command is used to set the TCP MSS in translated or encapsulated packets.

Declaration and implementation

Declaration: map_tcp_mss_command (src/plugins/map/map.c line 2019)

Implementation: map_tcp_mss_command_fn.

map params traffic-class

Summary/usage

map params traffic-class {0x0-0xff | copy}.

Description

Set or copy the IP TOS/Traffic Class field

Example usage
vpp# map params traffic-class

This command is used to set the traffic-class field in translated or encapsulated packets. If copy is specifed (the default) then the traffic-class/TOS field is copied from the original packet to the translated / encapsulating header.

Declaration and implementation

Declaration: map_traffic_class_command (src/plugins/map/map.c line 2003)

Implementation: map_traffic_class_command_fn.
