Procedure

  1. To enter User EXEC mode, log on to the switch.
  2. Display IS-IS Link State Database information by TLV:

    show isis lsdb tlv <1–236> [sub-tlv <1–3>][detail]

  3. Display IS-IS Link State Database information by Link State Protocol ID:

    show isis lsdb lspid <xxxx.xxxx.xxxx.xx-xx> tlv <1–236> [sub-tlv <1–3>] [detail]

Example

Display TLV information:
