IPv4 table operation
The IPv4 table, which contains the active IP multicast addresses the switch is currently supporting, has 128k
entries. However, the IPv4 table also contains IP host entries for every IP source or destination that the switch
has learned, as well as ACL flow entries. Entries in this table are generally aged-out if they are unused for 5
minutes or more.
Messages related to PIM operation
These messages appear in the Event Log and, if syslog debug is configured, in the designated Debug
destinations.
NOTE:
The
[
counter
]
value displayed at the end of each PIM Event Log message (and SNMP
trap messages, if trap receivers are configured) indicates the number of times the switch has
detected a recurring event since the last reboot. See the
Management and Configuration Guide
for
your switch.
Message
Meaning
alpha-string
pkt, src IP
ip-addr
vid
vlan-id
(not a nbr) (
counter
)
A PIM packet arrived from another router for which
no neighbor was found. May indicate a
misconfiguration between the sending and receiving
router. May also occur if a connected router is
disconnected, then reconnected.
Bad TTL in State Refresh pkt from IP
source-ip-addr
(
counter
)
The switch detected a TTL of 0 (zero) in the PIM
portion of a state-refresh packet. (This is not the IP
TTL.)
Failed alloc of HW
alpha-str
for flow
multicast-address
,
source-address
(
dup-msg-cnt
)
There are more than 2046 active flows. The switch
routes the excess through software, which
processes traffic at a slower rate. If this will be an
ongoing or chronic condition, transfer some of the
flows to another router.
Failed to alloc a PIM
data-type
pkt (
counter
)
The router was unable to allocate memory for a PIM
control packet. Router memory is oversubscribed.
Reduce the number of VLANs or increase the hello
delay and/or the override interval to reduce the
number of simultaneous packet transmissions. If the
number of flows exceeds 2046, the excess flows
are routed in software, which reduces the number of
packet transmissions. In this case, reducing the
number of flows by moving some clients to other
routers can help.
Failed to initialize
text-str
as a call back routine (
counter
)
Indicates an internal error. Report the incident to
your customer care center and reinstall the router
software.
