F3215-HP Load Balancing Module System Maintenance Command Reference-6PW101

9
Parameters
-f first-ttl: Specifies the first TTL, or, the allowed number of hops for the first packet. It ranges from 1 to 255
and defaults to 1, and must be less than the maximum TTL.
-m max-ttl: Specifies the maximum TTL, or, the maximum allowed number of hops for a packet. It ranges
from 1 to 255 and defaults to 30, and must be greater than the first TTL.
-p port: Specifies the UDP port number of the destination, which ranges from 1 to 65535 and defaults to
33434. It is unnecessary to modify this parameter.
-q packet-number: Specifies the number of probe packets sent each time, which ranges from 1 to 65535
and defaults to 3.
-vpn-instance vpn-instance-name: Specifies the VPN to which the destination belongs, where
vpn-instance-name is a case-sensitive string of 1 to 31 characters. If the destination is on the public
network, do not specify this option.
-w timeout: Specifies the timeout time of the reply packet of a probe packet, which ranges from 1 to
65535 milliseconds and defaults to 5000 milliseconds.
host: IPv6 address or host name of the destination, which is a string of 1 to 255 characters.
Usage guidelines
In the event of network failure, you can use the tracert command to determine the failed nodes.
Output from the tracert ipv6 command includes IPv6 addresses of all the Layer 3 devices the packets
traverse from source to destination. Asterisks (* * *) are displayed if the device cannot reply with an
ICMP error message (probably because the destination is unreachable or sending ICMP
timeout/destination unreachable packets is disabled).
To abort the tracert operation during the execution of the command, press Ctrl+C.
Examples
# View the path the packets traverse from source to destination with IPv6 address 2001::1.
<Sysname> tracert ipv6 2001::1
traceroute to 2001::1 30 hops max,60 bytes packet, press CTRL_C to break
1 2001::1 3 ms <1 ms 19 ms
# View the path the packets traverse from source to destination with IPv6 address 2001::1 in VPN 1.
<Sysname> tracert ipv6 –vpn-instance vpn1 2001::1
traceroute to 2001::1 30 hops max,60 bytes packet, press CTRL_C to break
1 2001::1 3 ms <1 ms 19 ms
