Brocade 7840 FCIP monitoring using MAPS
MAPS can monitor the Brocade 7840 platform for tunnel-level Quality of Service (QoS), state changes,
and throughput, and circuit-level jitter and round-trip duration.
QoS monitoring for the Brocade 7840 platform using MAPS is done at the tunnel level using the pre-
defined QoS priorities of High, Medium, Low, and F-class. MAPS monitors the state changes and
throughput of each individual tunnel using these priorities. The attributes monitored for QoS are
throughput and packet loss.
For tunnel-level monitoring, MAPS can track the predefined groups ALL_TUNNELS,
ALL_TUNNEL_HIGH_QOS, ALL_TUNNEL_MED_QOS, ALL_TUNNEL_LOW_QOS, and
ALL_TUNNEL_F_QOS. These groups correspond to the Brocade 7840 platform tunnels.
For circuit-level monitoring, the ALL_CIRCUITS group is monitored for round trip time (RTT) and
connection variance (Jitter) in addition to the CIR_STATE, CIR_UTIL, and CIR_PKTLOSS
parameters.
The available statistics are broken out in the following table, and rules corresponding to these statistics
are in the default policies.
