Cisco IP Transfer Point MSU Rates Msu Traffic Table

1.3.6.1.4.1.9.9.529.1.2.2

This table provides information on the traffic in MUS for each processor in both directions. Any MSU in which a processor is involved will be counted. Here are some examples of how MSUs would be counted. Traditional SS7 Links: MSU is received on Line card 1 that supports SS7 link and MSU is routed directly to line card 2 that supports output link. Line card 1 processor information will be updated to indicate it received MSU and line card 2 processor information will be updated to indicate it sent MSU. IP/SCTP based SS7 Links: IP based SS7 Links can be terminated on linecard or owned by the main processor. When SS7 link is terminated on main processor only the main processor information will be updated. The line card processor that owns the IP interface will be involved but will not be included in measurements. When the SS7 link is terminated on line card its processor information will be updated. It is important to note that packets exchanged for SCTP associations are different from SS7 MSUs. More than one SS7 MSU can be transmitted in a single IP packet. Also, the SCTP association exchanges control packets that are not counted as SS7 MSUs.
