PIM-DM (Dense Mode)
Messages Related to PIM Operation
Message Meaning
Rcvd pkt from rtr < ip-address >, unkwn
A packet received from the router at < ip-address > is an
pkt type < value > (<counter>)
unknown PIM packet type. (The < value > variable is the
numeric value received in the packet.)
Rcvd pkt ver# < ver-num >, from
The versions of PIM-DM on the sending and receiving
< ip-address >, expected < ver-num >
routers do not match. Differing versions will typically be
compatible, but features not supported in both versions will
(<counter>)
not be available.
Rcvd unkwn addr fmly < addr-type > in
The router received a PIM packet with an unrecognized
< text-str > pkt from < ip-addr > (<counter>)
encoding. As of February, 2004, the router recognizes IPv4
encoding.
Rcvd unkwn opt < opt-nbr > in < text-string >
The router received a PIM packet carrying an unknown PIM
pkt from < ip-addr > (<counter>)
option. The packet may have been generated by a newer
version of PIM-DM, or is corrupt. In most cases, normal
PIM-DM operation will continue.
Send error(< failure-type >) on
Indicates a send error on a packet. This can occur if a VLAN
< packet-type > pkt on VID < vid >
went down right after the packet was sent. The message
(<counter>)
indicates the failure type, the packet type, and the VLAN ID
on which the packet was sent.
Unable to alloc < text-str > table
The router was not able to create some tables PIM-DM
(<counter>)
uses. Indicates that the router is low on memory resources.
Remedies include one or more of the following:
• Reduce the number of configured VLANs by moving
some VLANs to another router.
• Free up system resources by disabling another feature,
such as one of the spanning-tree protocols or either the
RIP or the OSPF routing protocol. (Unless you are using
static routes, you will need to retain a minimum of one
unicast routing protocol.) Another option that may help
is to reduce the number of configured QoS filters.
• Move some hosts that create multicast demand to
another router.
Unable to alloc a buf of size
< bytes > for < data-flow > (<counter>)
Multicast routing is unable to acquire memory for a flow.
Router memory is oversubscribed. Reduce the number of
VLANs or the number of features in use. Remedies include
one or more of the following:
• Reduce the number of configured VLANs by moving
some VLANs to another router.
• Free up system resources by disabling another feature,
such as one of the spanning-tree protocols or either the
RIP or the OSPF routing protocol. (Unless you are using
static routes, you will need to retain a minimum of one
unicast routing protocol.) Another option that may help
is to reduce the number of configured QoS filters.
• Move some hosts that create multicast demand to
another router.
