characters.
7 Set the time interval during which
statistics on the sub-interface load is

<TIME>
<TIME> – interval in seconds,
takes values of [5..150].
8 Set the lifetime of IPv4/IPv6 entries in
the ARP table studied on the given
interface (optionally).
esr(config-subif)# ip arp
reachable-time <TIME>
or
esr(config-subif)# ipv6 nd
reachable-time <TIME>
<TIME> – lifetime of dynamic
MAC addresses, in
milliseconds.
Allowed values are from 5000
to 100000000 milliseconds.
Real time of the entry update
varies from [0,5;1,5]*<TIME>.
9 Change MTU
(MaximumTransmitionUnit) size.
MTU above 1500 will be active only
when using the 'system jumbo-frames'
command
