alarm

The command sets alarm threshold values.

Syntax
alarm { facility <FACILITY-ALARMS> | memory <MEMORY-ALARMS> | process <PROCESS-ALARMS> } <VALUE>
no alarm { facility <FACILITY-ALARMS> | memory <MEMORY-ALARMS> | process <PROCESS-ALARMS> } <VALUE>
Parameters

<FACILITY-ALARMS> – thresholds of alarms connected with the environment (FAN speed, processor and sensors temperature).  Takes the following values:

  • fan-speed high – fan speed threshold expressed as a percentage of the maximum fan speed (0..100), when crossing which from the lowest values to the highest ones, SNMP trap eltexEnvFanSpeedHigh (alarm) is generated. The value of this threshold should be greater than alarm facility fan-speed low (for esr-100/200/1000/1200/1500/1700/3100);
  • fan-speed high – fan speed threshold expressed as a percentage of the maximum fan speed (0..100), when crossing which from the highest values to the lowest ones, SNMP trap eltexEnvFanSpeedHighOk (alarm recovery) is generated. The value of this threshold should be lower than alarm facility fan-speed high (for esr-100/200/1000/1200/1500/1511/1700/3100);
  • temperature cpu critical high – processor temperature threshold expressed as degrees Celsius (0..255), when crossing which from the lowest values to the highest ones, SNMP trap eltexEnvTempCritical (alarm) is generated. The value of this threshold should be the highest of all processor temperature thresholds;
  • temperature cpu critical low – processor temperature threshold expressed as degrees Celsius (0..255), when crossing which from the highest values to the lowest ones, SNMP trap eltexEnvTempCriticalOk (alarm recovery) is generated. The value of this threshold should be less than alarm facility temperature cpu critical high but more than alarm facility temperature cpu overheat high;
  • temperature <sensor> overheat high – sensor temperature threshold expressed as degrees Celsius (0..255), when crossing which from the lowest values to the highest ones, SNMP trap eltexEnvTempOverheat (alarm) is generated.

  • temperature <sensor> supercooling high – sensor temperature threshold expressed as degrees Celsius (0..255), when crossing its opposite value from the lowest values to the highest ones, SNMP trap eltexEnvTempSupercoolingOk (alarm recovery) is generated. This threshold is intended to specify negative temperatures, its value should be less than alarm facility temperature <sensor> supercooling low;
  • temperature <sensor> supercooling low – sensor temperature threshold expressed as degrees Celsius (0..255), when crossing its opposite value from the highest values to the lowest ones, SNMP trap eltexEnvTempSupercooling (alarm) is generated.

traceroute

The command is used to trace a route to a specified network device.

Syntax
traceroute [ vrf <VRF> ] { <ADDR> | ip { <ADDR> | <HOSTNAME> } | ipv6 { <IPV6-ADDR> | <HOSTNAME> } } [ first-ttl <FIRST-TTL> ] [ max-ttl <MAX-TTL> ] [ timeout <TIMEOUT> ] [ source { ip { <SRC-ADDR> | <SRC-IPV6-ADDR> } | interface <IF> | tunnel <TUN> } ] [ dscp <DSCP> ] [ protocol { icmp | udp [ <PORT> ] | tcp [ <PORT> ] } ] [ gateway { <GW-ADDR> | <GW-IPV6-ADDR> } ]
Parameters

<VRF> – VRF instance name, set by the string of up to 31 characters;

<ADDR> – device IP address, defined as AAA.BBB.CCC.DDD where each part takes values of [0..255];

<IPV6-ADDR> – device IPv6 address, defined as X:X:X:X::X where each part takes values in hexadecimal format [0..FFFF];

<HOSTNAME> – user DNS name, set by the string of up to 255 characters;

<FIRST-TTL> – IP packet life time, the value from which a route tracing starts, takes values in the range of [1..255], 1 by default;

<FIRST-TTL> – IP packet life time, the value at which a route tracing stops, takes values in the range of [1..255], 30 by default;

<TIMEOUT> – timeout when waiting for the respond, in seconds. The option affects the timeout if there are no any responds, otherwise the utility waits for RTTs. Takes values in the range of [1..60], 5 seconds by default;

<SRC-ADDR> – source IP address, any router IP address may be used as the given address, defined as AAA.BBB.CCC.DDD where each part takes values of [0..255];

<SRC-IPV6-ADDR> – source IPv6 address, any router IPv6 address may be used as the given address, defined as X:X:X:X::X where each part takes values in hexadecimal format [0..FFFF];

<IF> – name of router interface through which the packets will be sent, specified in the form which is described in Section Types and naming order of router interfaces;

<TUN> – name of router tunnel through which the packets will be sent, specified in the form which is described in Section Types and naming order of router tunnels;

<DSCP> – DSCP priority according to RFC 2474, takes the value of [0..63], default value is 0;

<PORT> – TCP/UDP port number, takes the value of [1..65535], default value is 53 for UDP and 80 for TCP;

<GW-ADDR> – gateway IP address, defined as AAA.BBB.CCC.DDD where each part takes values of [0..255]. When specifying the parameter, IP source routing option, signalling to the router through which gateway the packet should be routed in a network, is added to an outgoing packet. For reasons of safety, the routing via this option is disabled on the most routers;

<GWIPV6-ADDR> – gateway IPv6 address, defined as X:X:X:X::X where each part takes values in hexadecimal format [0..FFFF]. When specifying the parameter, IP source routing option, signalling to the router through which gateway the packet should be routed in a network, is added to an outgoing packet. For reasons of safety, the routing via this option is disabled on the most routers.

verify filesystem

This command starts the process of calculating the hash sums for all the system files of the router and comparing them with the reference values. As a result, information on the compliance of the calculated hash amounts with the reference is displayed.

Syntax
verify filesystem [detailed]
Parameters

detailed – key, that responsible for the detailed display of information about the verification of each file.
