Rules on slow FA connections

Indeni
#1

Rule raises warning for slow Fa infterface speed, suggesting 1Gbps. Fa supports max of 100Mbps. Can the rule be modified to take into account interface type before alerting user?

#2

We'll have a rule writer look at this. If we collect a metric for max speed per interface, The rule could be modified. cross_vendor_network_port_speed_low



#3

I don't remember if the show interface command actually provides the max speed of the interface. Do you or know?

#4

This is what our IND script parses. Interesting choice, but for interface speed, we search in "x" in "xEthernet1/0/1" and if x=fast, speed = 100M. I may be looking at the wrong one. https://bitbucket.org/indeni/indeni-knowledge/raw/f01f85680a6638328635dfa03e207f58f97cf6fa/parsers/cisco/ios/show_interfaces.ind




if ( line ~ /[D|d]uplex/ ) {
# Extract duplex
duplex = trim(field[1]);
gsub(/,/, "", duplex);
#sub(/-[D|d]uplex/, "", duplex);

metric_tags["im.dstype.displayType"] = ""
writeComplexMetricString("network-interface-duplex", metric_tags, duplex)

# Extract speed
split(line, sp, ",");
speed = trim(sp[2]);
gsub(/,/, "", speed)

metric_tags["im.dstype.displayType"] = ""

if (interface ~ /[Ff]ast/) { speed = "100M"}
if (interface ~ /[Gg]iga/) { speed = "1G"}
if (interface ~ /[Tt]en/) { speed = "10G"}
if (interface ~ /[Ff]or/) { speed = "40G"}
if (interface ~ /[Hh]un/) { speed = "100G"}

writeComplexMetricString("network-interface-speed", metric_tags, speed)

}
}


--------------------------


If this is how we parse for the current interface speed, then we should parse that data as a metric "interface-maximum-speed" instead. There are several other values we can look at to parse metric "network-interface-speed" for current configuration and change the alert to "Interface is configured at a lower speed than maximum".
