Table 23‑2. vMotion Interoperability with port mirroring
Port mirroring session
type Source and destination
Interoperable with
vMotion Functionality
Distributed Port Mirroring Non-uplink distributed
port source and destination
Yes Port mirroring between
distributed ports can only be
local. If the source and
destination are on different
hosts due to vMotion,
mirroring between them will
not work. However, if the
source and destination move
to the same host, port
mirroring works.
Remote Mirroring Source Non-uplink distributed
port source
Yes When a source distributed
port is moved from host A to
host B, the original
mirroring path from the
source port to A's uplink is
removed on A, and a new
mirroring path from the
source port to B's uplink is
created on B. Which uplink
is used is determined by the
uplink name specified in
session.
Uplink port destinations No Uplinks can not be moved
by vMotion.
Remote Mirroring
Destination
VLAN source No
Non-uplink distributed
port destination
Yes When a destination
distributed port is moved
from host A to host B, all
original mirroring paths
from source VLANs to the
destination port are moved
from A to B.
Encapsulated Remote
Mirroring (L3) Source
Non-uplink distributed
port source
Yes When a source distributed
port is moved from host A to
host B, all original mirroring
paths from the source port to
destination IPs are moved
from A to B.
IP destination No
Distributed Port Mirroring
(legacy)
IP source No
Non-uplink distributed
port destination
No When a destination
distributed port is moved
from host A to host B, all
original mirroring paths
from source IPs to the
destination port are invalid
because the port mirroring
session source still sees the
destination on A.
TSO and LRO
TCP Segmentation Offload (TSO) and large receive offload (LRO) might cause the number of mirroring
packets to not equal to the number of mirrored packets.
