RLM Manager.
1. Sel e c t ,QWHUIDFH (WKHUQHW from the pull-down me nu to display the
statistics for the Ethernet interfac e.
2. Compare the number of ,QHUURUV with the number of %ULGJHLQ
SDFNHWV.
• When the number of “In errors” is 1% or more of the “Bridge in
packets”, this may indicate a cabling problem.
3. Compare the number of packets 2XWHUURUV with the number of %ULGJH
RXWSDFNHWV.
• When the number of “Out errors” is 1% or more of the “Bridge out
packets”, it is likely that there is a cabling problem.
4. Compare the number of 2XWFDUULHUVHQVHHUURUV with the number of
%ULGJHRXWSDFNHWV.
• When the number of “Out carrier sense errors” is 1% of the
“Bridge out packets” or the value of the “Out carrier sense errors”
increases too rapidly, this indicates insufficient space on the
network due to a backbone overload, or faulty cabling.
