| Description | Describes a particular port copy extension entry.
When creating an entry in this table using the 'createAndwait'
method, the following rules are applied:
- no SPAN consistency check is done for the entry until
the entry is activated. An entry will not be activated
if it fails the SPAN consistency check described for
the 'createAndGo' method.
-an instance remains in the 'notReady' state until the
associated portCopyStatus changes to 'active'.
When the agent processes a request of adding an entry
using 'createAndGo' method or a request that sets the value
of portCopyStatus object to 'active', the following rules
are applied:
The agent will add the entry to a SPAN session having the same
portCopySessionNo, or create a new session if it does not
exist. To join an existing session, either portCopySource or
portCopyDest, but not both, must exist in one of the entries
from the same SPAN session. In addition, the following actions
will be taken after a successful join:
1. The portCopyDirection, portCopyLoVlanMask, and
portCopyHiVlanMask values will overwrite the existing
values associated with this port copy session.
2. The portCopyDestLoVlanMask, portCopyDestHiVlanMask, and
portCopyOption values will overwrite the existing values
associated the same portCopyDest and this port copy session.
3. If the value of portCopyDest object does not exist in the
existing SPAN session, each of the ports identified in the
portCopySource is added to this SPAN session.
For example, given an existing SPAN session having ports
1, 2, and 3 as source ports, and port A as the destination
port, if an entry is added by an NMS with indices of (2,B),
the agent will also add entries for the other source ports
(e.g. (1,B) and (3,B)) to the session. The same algorithm
for adding entries will be applied if the portCopySource
does not already belong to this SPAN session.
When the agent processes a request to change the RowStatus of
an entry from 'active' to 'notInService', the following
rules are applied:
- That entry will be removed from its participating SPAN
session. The new RowStatus state will be 'notInService'.
- all entries in the table that have the same value of
portCopySessionNo and same value of portCopySource are
also set to 'NotInService'.
When agent processes a request to delete an entry, the
following rules are applied:
- the entry is simply removed if it is not currently active.
- if the portCopySessionNo value is non-zero and the value of
portCopyRemoveSrc object is set to 'true', then all entries
with the same value of portCopySessionNo and same value of
portCopySource are deleted.
- if the portCopySessionNo value is non-zero and the value of
portCopyRemoveSrc object is set to 'false', then all entries
with the same value of portCopySessionNo and same
value of portCopyDest are deleted.
- if the last portCopy entry is removed from a session,
then the session information is also removed. |
