پهنای باند مصرفی در سیسکو
برای مشاهده متوسط پهنای باند مصرفی یک اینترفیس در سیسکو از دستور show interfaces به صورت زیر استفاده میکنیم.
CISCO-RT#show interfaces fastEthernet 0/0/0
FastEthernet0/0/0 is up, line protocol is up
Hardware is FastEthernet, address is 6073.5c5a.21a1 (bia 6073.5c5a.21a1)

CISCO-RT#
CISCO-RT#show interfaces fastEthernet 0/0/0 | include rate
Queueing strategy: fifo
5 minute input rate 5717000 bits/sec, 957 packets/sec
5 minute output rate 1252000 bits/sec, 682 packets/sec
این دستور متوسط پهنای باند مصرفی ۵ دقیقه گذشته را نشان میدهد.
برای تغییر این زمان به صورت زیر عمل میکنیم. در این مثال این مقدار به ۳۰ ثانیه تغییر پیدا کرده است:
CISCO-RT(config)#int fa 0/0/0 CISCO-RT(config-if)#load-interval ? <30-600> Load interval delay in seconds CISCO-RT(config-if)#load-interval 30 CISCO-RT#show interfaces fastEthernet 0/0/0 | include rate Queueing strategy: fifo 30 second input rate 6948000 bits/sec, 1057 packets/sec 30 second output rate 1389000 bits/sec, 759 packets/sec CISCO-RT#
