Cisco show etherchannel всегда нулевая загрузка?

Есть на cat 3570x (15.2(4)E10) несколько lacp etherchannel-ов.

Как бы их не нагружал LOAD  на портах всегда ноль-повдоль. В интернетах пишут, что, должно показывать нагрузку на порты.

 

c3750x-24-core#sh etherchannel 4 port-channel
                Port-channels in the group:
                ---------------------------
Port-channel: Po4    (Primary Aggregator)
------------
Age of the Port-channel   = 0d:03h:06m:21s
Logical slot/port   = 10/4          Number of ports = 2
HotStandBy port = null
Port state          = Port-channel Ag-Inuse
Protocol            =   LACP
Port security       = Disabled
Load share deferral = Disabled

Ports in the Port-channel:

Index   Load   Port     EC state        No of bits
------+------+------+------------------+-----------
  0     00     Gi1/0/23 Active             0
  0     00     Gi1/0/24 Active             0

Time since last port bundled:    0d:03h:06m:10s    Gi1/0/24
Time since last port Un-bundled: 0d:03h:13m:20s    Gi1/0/24

Нагрузил по гланды - до 2 гбит с помощью 3 машинок (у одной intel nic teaming драйвером под виндой).

Просто на интерфейсе нагрузку пишет txload 251/255 :

c3750x-24-core#sh int po4
Port-channel4 is up, line protocol is up (connected)
  Hardware is EtherChannel, address is 2894.0f02.3818 (bia 2894.0f02.3818)

     reliability 255/255, txload 251/255, rxload 1/255

Включил хистори на интерфейсе - тоже :

Тоже с загрузкой всё в порядке. Кто-нибудь знает, что это за load такой?

Не знаю, как на 3570x, но на 4948e и 3750g тоже нули при идеальной почти балансировке.

4500x такая же херня.

Видимо, это фишка исключительно шеститонников и нексусов. У нексуса тоже куча параметров для настройки балансировки - https://www.cisco.com/c/en/us/td/docs/switches/datacenter/sw/6_x/nx-os/interfaces/configuration/guide/b-Cisco-Nexus-7000-Series-NX-OS-Interfaces-Configuration-Guide-6x-Book/configuring_port___channels.html
