show ipv6 access-list

To display the IPv6 access list, use the show ipv6 access-list command in privileged EXEC mode. The IPv6 access list determines what IPv6 traffic can pass through the ASA.

Syntax Description

any	(Optional) An abbreviation for the IPv6 prefix ::/0.
host source-ipv6-address	(Optional) IPv6 address of a specific host. When provided, only the access rules for the specified host are displayed.
id	(Optional) The access list name. When provided, only the specified access list is displayed.
source-ipv6-prefix /prefix-length	(Optional) IPv6 network address and prefix. When provided, only the access rules for the specified IPv6 network are displayed.

Usage Guidelines

The show ipv6 interface command provides output similar to the show interface command, except that it is IPv6-specific. If the interface hardware is usable, the interface is marked up. If the interface can provide two-way communication, the line protocol is marked up.

Examples

The following is sample output from the show ipv6 interface command:

hostname# show ipv6 interface outside

interface ethernet0 "outside" is up, line protocol is up

  IPv6 is enabled, link-local address is 2001:0DB8::/29 [TENTATIVE]

  Global unicast address(es):

    FF02::1:FF11:6770

  MTU is 1500 bytes

  ND DAD is enabled, number of DAD attempts: 1

  ND reachable time is 30000 milliseconds

  ND advertised reachable time is 0 milliseconds

  ND advertised retransmit interval is 0 milliseconds

  ND router advertisements are sent every 200 seconds

  ND router advertisements live for 1800 seconds

The following is sample output from the show ipv6 interface command when entered with the brief keyword:

Command History

Release	Modification
7.0(1)	This command was introduced.

Usage Guidelines

The following information is provided by the show ipv6 neighbor command:

•IPv6 Address—The IPv6 address of the neighbor or interface.

•Age—The time (in minutes) since the address was confirmed to be reachable. A hyphen (-) indicates a static entry.

•Link-layer Addr—The MAC address. If the address is unknown, a hyphen (-) is displayed.

•State—The state of the neighbor cache entry.

---

Note Reachability detection is not applied to static entries in the IPv6 neighbor discovery cache; therefore, the descriptions for the INCMP (Incomplete) and REACH (Reachable) states are different for dynamic and static cache entries.

---

The following are possible states for dynamic entries in the IPv6 neighbor discovery cache:

–INCMP—(Incomplete) Address resolution is being performed on the entry. A neighbor solicitation message has been sent to the solicited-node multicast address of the target, but the corresponding neighbor advertisement message has not yet been received.

–REACH—(Reachable) Positive confirmation was received within the last ReachableTime milliseconds that the forward path to the neighbor was functioning properly. While in REACH state, the device takes no special action as packets are sent.

–STALE—More than ReachableTime milliseconds have elapsed since the last positive confirmation was received that the forward path was functioning properly. While in STALE state, the device takes no action until a packet is sent.

–DELAY—More than ReachableTime milliseconds have elapsed since the last positive confirmation was received that the forward path was functioning properly. A packet was sent within the last DELAY_FIRST_PROBE_TIME seconds. If no reachability confirmation is received within DELAY_FIRST_PROBE_TIME seconds of entering the DELAY state, send a neighbor solicitation message and change the state to PROBE.

–PROBE—A reachability confirmation is actively sought by resending neighbor solicitation messages every RetransTimer milliseconds until a reachability confirmation is received.

–????—Unknown state.

The following are possible states for static entries in the IPv6 neighbor discovery cache:

–INCMP—(Incomplete) The interface for this entry is down.

–REACH—(Reachable) The interface for this entry is up.

· Interface

The interface from which the address was reachable.

Examples

The following is sample output from the show ipv6 neighbor command when entered with an interface:

hostname# show ipv6 neighbor inside

IPv6 Address                             Age Link-layer Addr State Interface

2000:0:0:4::2                              0 0003.a0d6.141e  REACH inside

The following is sample output from the show ipv6 neighbor command when entered with an IPv6 address:

hostname# show ipv6 neighbor 2000:0:0:4::2

IPv6 Address                             Age Link-layer Addr State Interface

9.0(1)	Added support for the failover, cluster, ospf, interface, and summary keywords.

Usage Guidelines

The show ipv6 route command provides output similar to the show route command, except that the information is IPv6-specific.

The following information appears in the IPv6 routing table:

•Codes—Indicates the protocol that derived the route. Values are as follows:

–C—Connected

–L—Local

–S—Static

–R—RIP derived

–B—BGP derived

–I1—ISIS L1—Integrated IS-IS Level 1 derived

–I2—ISIS L2—Integrated IS-IS Level 2 derived

–IA—ISIS interarea—Integrated IS-IS interarea derived

•fe80::/10—Indicates the IPv6 prefix of the remote network.

•[0/0]—The first number in the brackets is the administrative distance of the information source; the second number is the metric for the route.

•via ::—Specifies the address of the next router to the remote network.

•inside—Specifies the interface through which the next router to the specified network can be reached.

Note The clustering and failover keywords do not appear unless these features are configured on the ASA.
