+SRv6 Static SIDs Commands
+=========================
+
+.. clicmd:: segment-routing
+
+   Move from configure mode to segment-routing node.
+
+.. clicmd:: srv6
+
+   Move from segment-routing node to srv6 node.
+
+.. clicmd:: static-sids
+
+   Move from srv6 node to static-sids node. In this static-sids node, user can
+   configure static SRv6 SIDs.
+
+.. clicmd:: sid X:X::X:X/M locator NAME behavior <uN|uDT4|uDT6|uDT46> [vrf VRF]
+
+   Specify the locator sid manually. Configuring a local sid in a purely static mode
+   by specifying the sid value would generate a unique SID.
+   This feature will support the configuration of static SRv6 decapsulation on the system.
+
+   It supports four parameter options, corresponding to the following functions:
+   uN, uDT4, uDT6, uDT46
+
+   When configuring the local sid, if the action is set to 'uN', no vrf should be set.
+   While for any other action, it is necessary to specify a specific vrf.
