Viewing DvR host entries

About this task

View DvR host entries (IPv4 remote host routes) on either a Controller or a Leaf node. The node displays the host entries learned either locally on its Switched UNI port or dynamically from other nodes within the DvR domain.

Before you begin

Ensure that you enable DvR globally on the node.

Procedure

  1. Enter Privileged EXEC mode:

    enable

  2. View the DvR host entries.

    On a Controller:

    show dvr host-entries [domain-id <1–255>]|[ipv4 {A.B.C.D}]|[l2isid <1-16777215>]|[l3isid <0-16777215>]|[nh-as-mac]|[type <1–2>]|[vrf WORD<1-16>] [vrfids WORD<0-512>]

    On a Leaf node:

    show dvr host-entries [domain-id <1–255>]|[ipv4 {A.B.C.D}]|[l2isid <1-16777215>]|[l3isid <0-16777215>]|[nh-as-mac]|[type <1–2>]

    Viewing the DvR host entries for a specific VRF or VRF ID is not supported on a DvR Leaf node.

Example

View DvR host entries on either a Controller or a Leaf node.

Viewing the DvR host entries for a specific VRF or VRF ID is not supported on a DvR Leaf node.
