a LAG OID is not a valid target. The sampled branch in setUnsetPortMirror() previously called sai_port_api->set_port_attribute() unconditionally on port.m_port_id, so a sampled mirror session bound to a LAG source port silently failed at the SAI layer. Extract the per-PHY sampled-mirror logic (conflict check + 2-attr set with rollback) into setUnsetSampledMirrorOnPhyPort() and dispatch in setUnsetPortMirror() based on port type: - LAG: iterate getLagMember() and apply helper to each PHY member (consistent with the existing full-mirror LAG path) - PHY: call helper directly - other: reject with LOG_ERROR Behavior on PHY source ports is unchanged.

Rebuild from the full CONFIG_DB row on immutable-field updates. The delete+recreate path in updateEntry() used the SET event's data payload to build the new session. A partial SET (e.g. `redis-cli HSET MIRROR_SESSION|x dscp 16`) carries only the changed field, so the recreate dropped src_ip/dst_ip/gre_type/... and left a stripped-down (or failed) session. Read the full row from CONFIG_DB via a new m_cfgMirrorTable handle and hand that to createEntry() instead, so a partial payload no longer corrupts an otherwise valid session. 2. Keep TRUNCATE_ENABLE in sync with TRUNCATE_SIZE. The in-place truncate_size update set only SAI_SAMPLEPACKET_ATTR_TRUNCATE_SIZE and never touched SAI_SAMPLEPACKET_ATTR_TRUNCATE_ENABLE, leaving two 0 <-> non-zero transitions broken: - 0 -> non-zero: SIZE was set but ENABLE stayed false, so truncation remained disabled on the hardware. - non-zero -> 0: SIZE=0 was attempted while ENABLE was still true, which SAI may reject or interpret implementation-defined. Always set TRUNCATE_ENABLE based on the new size, and only set TRUNCATE_SIZE when enabling, mirroring the create-side logic in createSamplePacket(). 3. hdel stale sample_rate / truncate_size from STATE_DB. setSessionState() omits sample_rate and truncate_size from the FVT list when their values are 0. Table::set() does an HMSET-style merge in Redis and does not remove fields not present in the payload, so after a non-zero -> 0 transition the old value persisted in STATE_DB and no longer matched the in-memory session or the hardware. Explicitly hdel() those fields when they go to zero so STATE_DB stays consistent with the session state.

The sampled mirror feature now also binds these two slots, so any blind write from sFlow can silently overwrite a mirror-owned sample-packet object (and vice versa). 1. sflowUpdateSampleDirection: apply the same pre-check pattern already used by sflowAddPort. The function unconditionally writes both INGRESS and EGRESS SAMPLEPACKET_ENABLE during direction changes (rx<->tx, rx<->both, tx<->both), so a slot owned by another feature could be silently overwritten. For any direction we are about to set to a non-NULL OID, fetch the current binding first and refuse the update if it is owned by something other than sFlow or this session. Both directions are checked before any write so a conflict on the second direction never leaves the first half-applied. 2. sflowAddPort: rollback restores the previous ingress OID instead of clearing it. On rate updates sFlow creates a new sample-packet object and calls sflowAddPort to rebind the port to the new OID. The ingress slot at that moment already holds the previous valid sFlow sample_id, not NULL. If the subsequent egress write fails the previous rollback (set ingress = NULL) would wipe out the still-valid old binding and leave sFlow ingress sampling completely off, which is worse than the original failure. Capture the previous ingress OID via get_port_attribute before the new write, and restore it on rollback so the port returns to its pre-call state on failure.

Exercise updateEntry on full <-> sampled transitions. The two PathTransition* tests used a full delete + recreate sequence (remove route/neighbor/ip, remove_mirror_session, create_erspan_session, re-add plumbing) to switch a session between full and sampled modes. That sequence dispatches through MirrorOrch's top-level deleteEntry + createEntry path and never exercises the new updateEntry transition logic that handles a sample_rate 0 <-> non-zero change in place. Replace the delete+recreate block with a single in-place config_db.set_field(MIRROR_SESSION, session, "sample_rate", "50000" or "0"). This sends a partial SET (only sample_rate) on an already-existing key, which is routed to MirrorOrch::updateEntry and hits both the new `(old_rate == 0) != (new_rate == 0)` immutable-transition branch and the full-row CFG_DB rebuild on the recreate. Route/neighbor/IP plumbing is left in place across the transition since the session key never leaves CONFIG_DB. 2. Add a synchronization point to the reject tests. The three SampledMirrorInvalid* tests (TX direction, truncate without sample_rate, BOTH direction) wrote an invalid config to CONFIG_DB and then immediately called wait_for_deleted_entry on STATE_DB. Because the STATE_DB entry for a rejected session is never created in the first place, that assertion can pass trivially before orchagent has even consumed the CONFIG_DB notification - so a regression that silently accepts the invalid config would not fail the test. Insert time.sleep(1) before the assertion in each of the three reject tests so orchagent has time to consume and reject the config first. This matches the synchronization style already used throughout test_mirror.py and other SwSS VS tests.

All three tests exercise the EGRESS code path because SAI VS installs a tap-interface gated preSetPort handler on INGRESS_SAMPLEPACKET_ENABLE (VirtualSwitchSaiInterfacePort.cpp::preSetPort) that fails in mock tests with SAI_STATUS_FAILURE; the conflict pre-check itself is symmetric across directions so the EGRESS path covers the shared logic. Extends Portal::SflowOrchInternal with helpers to invoke the relevant private methods and seed internal maps from tests. Also mark the sflowAddPort Phase 2 SAI failure branches LCOV_EXCL_LINE: the ingress set_port_attribute failure path and the egress failure + ingress rollback path cannot be exercised by mock tests because SAI VS set_port_attribute always returns SUCCESS for the EGRESS attribute and fails uniformly on INGRESS; covering them would require SAI failure injection.
