Trunk mode in SLM224P switches

Hello, can someone please tell me how to create trunk in SLM224P switches ?
As it is possible, I think I should do it that way:
create the same vlans (all vlans) on both switches
set ports whitch sw1 and sw2 are connected as tagged
rest of ports untagged ?
2 switchers are connected by ports which have the same vlan sw1 connected to bgp router, sw2 stands alone.
This does not working, any ideas ??
Best regards and sorry for my english

I suggest configuring both switches with VLANs, member ports to a specific VLAN and connect PC's set with static IP addresses on switch 1 and 2. In this way, you can see if both switches will work when PC's connected to same VLAN on switch 1 and 2 communicate by PING.
Hope this helps!

%EC-SP-5-CANNOT_BUNDLE2 - Switch incorrectly sees port in Dynamic Trunking Mode

Take this configuration on a 6500 with 2 WS-X6716-10-GE modules installed.

Now I do this:

no shut
This error message is generated:
%EC-SP-5-CANNOT_BUNDLE2: Te2/1 is not compatible with Te1/1 and will
be suspended (trunk mode of Te2/1 is trunk, Te1/1 is dynamic)
The million dollar question - Why would it see Te1/1 as being in dynamic trunking mode?

glen.grant wrote: Shutdown the port channel by shutting down the port channel SVI . Then try to bring it up , with a no shut on the port channel SVI , this will bring both ports up at the same time. Sometimes they do not like having a single port in the channel being brought up by itself. Also make sure the other end matches exactly seeing you are forcing the port channel to an on state.
I agree this may work, but it doesn't really address the problem. If both the logical and physical interfaces have 'switchport nonegotiate' configured, why would the switch see it in Dynamic Trunking mode?
One thing I did try was removing 'switchport nonegotiate' from Te2/1. Then I got this:
%EC-SP-5-CANNOT_BUNDLE2: Te2/1 is not compatible with Te1/1 and will be suspended (dtp nonegotiate of Te2/1 is 0, Te1/1 id 1)
It's now saying DTP is disabled for Te1/1. In other words, it is NOT in dynamic trunking mode. Since that directly contradicts the earlier message, my conclusion is this is a software bug.

Server Port - Trunk Mode

Hi,
One of the Server ports (pointing towards a UCS Chassis) on my fabric interconnect is currently showing as down as it is Trunk mode not Fabric Mode as per all the other server ports.
For some reason when I look under the LAN tab this one interface is showing under "internal LAN". I have tried disabling and/or deleting the interface from under "internal LAN" however every time I re-configure the port as a Server Port it is showing back under and the mode remains in Trunk.
Does anyone have some advice how I can get this port out of Trunk Mode and into Fabric Mode?
Many Thanks, Paul

Switchport trunk encapsulation on L3 switches

Why is 'switchport trunk encapsulation <dot1q or isl> required on L3 switches? The default trunk encapsuation mode on 'modern' Cisco switches is to 'auto' negotiate, so why doesn't 'auto-negotiate' work when configured from the L3 switch port? If I configure 'switchport mode trunk' on an L2 switch (capable of only dot1q) and don't configure the adjacent L3 port, the trunk is auto-negotiated. However, if I configure 'switchport mode trunk' on the L3 port first, it gives the error we've all witnessed: Command rejected: An interface whose trunk encapsulation is "Auto" can not be configured to "trunk" mode. Interestingly, if I configure, 'switchport mode dynamic desirable' on the L3 port, the interface does indeed negotiate the trunk encapsulation and establish the trunk. According to Cisco documentation, the 'switchport mode trunk' command is also supposed to negotiate the trunking status and encapsulation--so why doesn't this command work the same as 'switchport mode dynamic desirable?'

John,
You're absolutely correct. My hope is that Cisco will change its definition for 'switchport mode trunk.'
This is from their documentation:
switchport mode dynamic desirable
Makes the interface actively attempt to convert the link to a trunk link. The interface becomes a trunk interface if the neighboring interface is set to trunk, desirable, or auto mode.
switchport mode trunk
Puts the interface into permanent trunking mode and negotiates to convert the neighboring link into a trunk link. The interface becomes a trunk interface even if the neighboring interface is not a trunk interface.
switchport nonegotiate
Prevents the interface from generating DTP frames. You can use this command only when the interface switchport mode is access or trunk. You must manually configure the neighboring interface as a trunk interface to establish a trunk link.
I've highlighted negotiates to point out that DTP frames are still sent to the neighboring device to negotiate the trunking status. Therefore, why doesn't it also negotiate the encapsulation type when desiring to trunk? My point being, if it's going to trunk unconditionally and not negotiate the trunking protocol, and since you'd have to have an ISL-only switch (non-extant), Cisco should simply get rid of ISL on their switches or have the 'negotiation' process or (unconditional state) select dot1Q as the trunking protocol.

Trunk Confiugration on ME4900 Switch

Hello Technical Team,
We have 2 Cisco ME4900 Switch with 3 Modules inside: Below are the detail for the Module:
Mod Ports Card Type                              Model              Serial No.
---+-----+--------------------------------------+------------------+-----------

2    24 10GE (X2), 1000BaseX (SFP)             WS-X4908-10GE
3    20 10/100/1000BaseT (RJ45)                WS-X4920-GB-RJ45
I am trying to build trunk between these 2 Switches by using 10GE(X2) 1000Base X (SFP) Ports but unfortunately I am fail to do that. Is there any specific Command to make trunk or port channel between 2 ME-4900 Switch?
Thanks,
JH

Hi RS,
I have below Modules:
1     8 4900M 10GE (X2)                        WS-C4900M
2    24 10GE (X2), 1000BaseX (SFP)    WS-X4908-10GE
3    20 10/100/1000BaseT (RJ45)          WS-X4920-GB-RJ45
If I do show run then I have follow Ports order:
1     8 4900M 10GE (X2)      WS-C4900M
interface TenGigabitEthernet1/1 TO TenGigabitEthernet1/8
2    24 10GE (X2), 1000BaseX (SFP)    WS-X4908-10GE
interface TenGigabitEthernet2/1 TO interface TenGigabitEthernet2/8
interface GigabitEthernet2/9 TO interface GigabitEthernet2/24
3    20 10/100/1000BaseT (RJ45)          WS-X4920-GB-RJ45
interface GigabitEthernet3/1 TO interface GigabitEthernet3/20
So i am going to use SFP base X2 Convertor for Trunk between another ME-4900 Switch so do do I use 2/9-10 ports from 1st 2 SFP Ports from GBIC?
Further what is the command to check the port group ?
Kindly see the SH running for your advice.
Thanks,
JH

Can I use straight cable to connect trunk ports between 2 switches?

Hi,
Am I able to use straight instead of cross cable to connect trunk ports between 2 switches??
thanks!

Hi Devang,
When a 10/100 Fast Ethernet interface is enabled, one end of the link must perform media dependent interface (MDI) crossover (MDIX), so that the transmitter on one end of the data link is connected to the receiver on the other end of the data link (a crossover cable is typically used).
The Auto-MDIX feature eliminates the need for crossover cabling by performing an internal crossover when a straight cable is detected during the auto-negotiation phase.
HTH, if yes please rate the post.

Crio-system in sleeping-mode or software-switching-off ?

hi,
i have a cRIO - 9012 system and i want to know, if anyone knows if it's possible to send a signal to a i/o module on the target that says that the cRIO-system should switch in a sleeping-mode or that switches it off. if it's possible how, and how can i turn it on again? maybe via the ethernet port ?
or does anyone know, if there is a module that has an elko or anything else, that can power the system for a few seconds after you switch the main power supply off ?
thanks for your replies,
simon

Hello Simon,
I think i may have found what you have been looking for:
http://digital.ni.com/public.nsf/allkb/AE7320AEEB6D77188625713B007EC2C4?OpenDocument
This Knowledgebase shows how to set the cRIO chassis and modules in sleep mode.
This "sleep mode" works only for the chassis (FPGA) therfore you will have implement "Wake on Lan" functionality in the Real Time part yourself.
There already is a Produkt suggestion for this feature so it may be implemented in the Future.
As far as i know there aint no C Series module providing a Capacitor huge enough to power the System for a few seconds.
But you can use standard Uninterruptible Power Supply (UPS) to power the System when the line voltage is missing.

Wetzer

802.1q trunk b/w 8PoE switch integrated in 1861 CME

Hi,
I have to deploy cme7.0 (1861). Actually two 1861 routers are bought but only one of them act as cme while the 8PoE integrated switch of other 1861 is used. half of the IP phones are connected to the 8PoE integrated switch in CME (1861 router) while half of the phones are connected to 8PoE of 1861 (only 1861's PoE is used in this setup). i want to know whether i can cascade the two switches or in other words whether i can form a 802.1q trunk b/w these switches to carry the voice and data vlans.

Yes, you can.

Private Vlans and trunk mode

if we have a primary vlan 100 associate with it
vlan 11 over {fa0/2 work as host mode} , vlan 12 over {fa0/3 work as host mode} they work as secondry community vlan
and vlan 13 as isolated secondry vlan over {fa0/4 host mode}
How we can route between private vlans 11,12,13 and {vlan 50 fa0/5 access mode}
cloud we use the fa 0/1 which connected to L3 device as promiscouous mode and trunk mode at the same time or what ... ??
and

Private vlan's are all on the same subnet, so from what you are writing I see:
100-------------------------------
| | |
| | |
11 12 13
Fa0/2 fa/03 fa0/4
and you want to route to Vlan 50, correct?
In that case you need to trunk vlan 100 to a vlan interface and make sure that vlan 50 also has a routed interface on the same device.

Hi, im having problems with my iphone it would always be showing up "No Service" even when I get my simcard out, when i turn airplane mode it would switch to " Searching" and then go back to "No Service", i have tried restoring several times, but nothing

Hi, im having problems with my iphone it would always be showing up "No Service" even when I get my simcard out, when i turn airplane mode it would switch to " Searching" and then go back to "No Service", i have tried restoring several times, but nothing has changed. I must say that my iphone was working perfectly until the last months my battery began to die all from a sudden, so my phone got turn off really frequently, so then i ordered a battery and changed it myself so when phone was on.. it had this problem.. im desperate here

No I haven´t take it to Apple Store, i think I will actually. My iphone was jailbroken and ulocked with gevey sim, but when this failures began i decided to restore it, and I did preserve the baseband, but when I took it into one of these "Places" they told me it would be a good idea to do a clean restore and see if this fixed the problem so I upgraded my baseband, and right now my iphone is freshly restore, no jailbreak no nothing.
Btw yes something like a year ago my screen was replaces by others not by apple, but I didnt had any issues after this.. until today (a little more than a year later).

Trunk mode vlan to a VM with 8 vNIC's - targetting one specific vNIC

Hi all
I've popped a question into the Powerhsell forum this morning, and realised it may have been more suitable in Hyper-V section due to the nature of the question. Apologies if dual posting is not the done thing.
My original question can be seen here:
https://social.technet.microsoft.com/Forums/scriptcenter/en-US/5b12e416-ffc9-4391-b3f1-91fdb192f11a/hyperv-trunk-mode-to-vm-how-to-target-a-specific-virtual-nic-using-powershell?forum=winserverpowershell
Essentially, my question is around a VM that currently has 8 x vNIC's, but needs to communicate over 9 x vlans at present. I have attempted the following command in a test environment, but I can't see how this would comms over a specific vNIC; it looks like
its a global command to the target VM:
Set-VMNetworkAdapterVlan -VMName test1 -Trunk -AllowedVlanIdList "1-5" -NativeVlanId 6
Is there a way to target a specific vNIC on a VM with the above command at all, or is there a better way to enable trunk mode to the intended VM please?
Thanks
Paul

Hi Eric
Thanks for reply.
Thanks - your reply got me thinking a little more about this, and I found another article (which was also a reply from yourself when someone asked about how you rename a network adaptor when every adaptor is called "Network Adapter"),
that lead to a working command for what I would like to achieve.
So, here is my working command now:
Get-VMNetworkAdapter -VMName test2 | Where-Object -Property MacAddress -eq "000000000098" | Set-VMNetworkAdapterVlan -Trunk -AllowedVlanIdList "2214-2217" -NativeVlanId 22
Upon running Get-VMNetworkAdapterVlan I can see how the various adaptors are now configured:
test2                    Network Adapter               Untagged
test2                    Network Adapter               Untagged
test2                    Network Adapter               Trunk    22,2214-2217
test2                    Network Adapter               Untagged
I appreciate my command may not be pretty, but it completes successfully in my lab in terms of applying the settings. Is there any obvious problems that you can see with the above?
Lastly, the reason for the vlans in this way is because the server is NetBackup Master Server, and needs comms over all the relevant vlans. I'm intending on configuring a secondary interface through the teaming GUI in Server 2012, and specifying vlan ID's
there.
Thanks

Trunking on older 3500XL switches

I probably already know the answer to this but is there a way to remove vlans 1 and 1002-1005 on a trunk port on a 3548-XL? I want to be able to connect an IP phone to the port and only allow traffic from my voice and the floor vlans (599 & 730) respectively. But when I run the command:
switchport trunk allowed vlan remove 1-598,600-729,731-1024
all the vlans are removed exept 1,599,730,1002-1005. I know that these are "special" vlans and these are older switches, but is there a way to remove them from a port on these switches?

If you want to configure the port for just voice vlan and data vlan then you need not to clear vlans out of the trunk, just configure voice vlan. This platform should support voice vlan. for example:
interface FastEthernet0/2
description DOT1Q port to IP Phone
switchport trunk encapsulation dot1q
switchport trunk native vlan 730
switchport mode trunk
switchport voice vlan 599
spanning-tree portfast
