Давайте разберемся в терминологии. Я просто видимо не так выразился, с помощью interface range я создаю группу интерфейсов, а потом объединяю их channel-group 1 mode desirable, но проблема в том, что интерфейсы которые начинаются с 0-1, объединяются, а вот эти начинаются с 3, 4, 5… Никак не выходит объединить) Добавлено через 13 минут

Если не сложно, подскажите можно ли агрегировать Gigabit и FastEthernet или лучше, что бы не замарачиваться обьединить 2 Gigabit Ethernet? Порты в etherchannel группе должны быть одной скорости.

192.168.1.1 can ping 192.168.1.2 ONLY
Cannot Ping 192.168.2.1 or 192.168.2.2
To be able to
ping an interface from the same device , some device
router/switch/hub
has to be
connected there.
To
go further we need to enable Routing Protocols or a Static Route.

Cisco recommends that the use of debug commands should
be performed
under the direction and guidance of specialized
technical personnel,
because they may lead to operation
disruption and even total device
failure.

CDP Protocol Cram
1.
CDP Stands for Cisco Discovery protocol.
CDP is primarily used to obtain protocol addresses of
neighbouring devices and discover the platform of those
devices. CDP can also be used
to display information about
the interfaces your router uses. CDP is
media- and protocol-
independent, and runs on all Cisco-manufactured
equipment
including routers, bridges, access servers, and switches.
2.
Runs on device running Cisco IOS.
3.
Commands
Router#show cdp neighbors detail
Router#show cdp entry *
Both show IP of immediately connected neighbors.
For Switch it will be VLAN IP
For Router it will be Router connected IP.
4.
Router(config)#cdp run ?
<cr>
Router(config)#no cdp run
Router#show cdp neighbors detail
% CDP is not enabled
5.
Can telnet into a device and than run CDP.
6.
Router(config)#int g0/0
Router(config-if)#cdp ?
enable Enable CDP on interface
Router(config-if)#cdp enable ?
<cr>
Router(config-if)#no cdp enable
Router#show cdp neighbors

We have recently started replacing switches in our network with New Cisco 2960S and 3560G switches. I have created a config template in notepad for the 2960s switches and all has been going smooth. That is until I pulled the 3560g into the mix. When I place that config template on the switch I get invalid input at marker in several different places. I am not sure why when this config works for all of our 2960s switches. The config is pasted below. Any help is greatly appreciated.

Hello Cisco folks,
I’m working on implementing some NSA SNAC Guide (excellent guides if you’re not familiar with them) suggestions for my Cisco Catalyst switches. I have three 24 port switches and one 48 port switch. They’re old, but I just upgraded the code to the latest available from Cisco yesterday.
The upgrade went fine, but the switches still don’t take the interface range command, i.e. interface range fa0/1 — 24. See output below:

I’m certain there’s a way to make a configuration change to multiple interfaces at the same time, but haven’t figured it out on my switches yet. Can anyone see what I’m doing wrong?
Thanks,
Ted
