terminal
Sets the number of lines to display on the terminal and enables logging.
Syntax
terminal {length lines | monitor}

traceroute
Displays the routes that packets take to travel to an IP address.
Syntax
traceroute host [-46dFITnreAUDV] [-f first_ttl] [-g gate,...] [-i device] [-m
max_ttl] [-N squeries] [-p port] [-t tos] [-l flow_label] [-w waittime] [-q
nqueries] [-s src_addr] [-z sendwait] [--fwmark=num] host [packetlen]
Parameters
• host — Enter the host to trace packets from.
• -i interface — (Optional) Enter the IP address of the interface through which traceroute sends packets.
By default, the interface is selected according to the routing table.
• -m max_ttl — (Optional) Enter the maximum number of hops (maximum time-to-live value) that
traceroute probes (default 30).
•
-p port — (Optional) Enter a destination port:
• For UDP tracing, enter the destination port base that traceroute uses (the destination port number is
incremented by each probe).
• For ICMP tracing, enter the initial ICMP sequence value (incremented by each probe).
• For TCP tracing, enter the (constant) destination port to connect.
• -P protocol — (Optional) Use a raw packet of the specied protocol for traceroute. Default protocol is
253 (RFC 3692).
• -s source_address — (Optional) Enter an alternative source address of one of the interfaces. By
default, the address of the outgoing interface is used.
• -q nqueries — (Optional) Enter the number of probe packets per hop (default 3).
• -N squeries — (Optional) Enter the number of probe packets that are sent out simultaneously to
accelerate traceroute (default 16).
• -t tos — (Optional) For IPv4, enter the Type of Service (TOS) and Precedence values to use. 16 sets a
low delay; 8 sets a high throughput.
