Trunking between a router and a switch

i used the topology and the configuration described on the pictures included on this post.. but the problem that the ping failed between the switch and the router

The router config might not have been captured correctly coz it would not allow you to configure the subinterface with no vlan id after the encapsulation. But you can try this, define the native vlan 1 on the router's subtinterface for subnet 172.16.1.0/24. Also, what address of the router are you pinging from the switch?

The difference of the IEEE802.1x Auth between Cisco Routers and Catalyst switches

Hello
I am investigating the difference of the IEEE802.1x Auth between Routers and Switches.
Basically dot1x auth is availlable on Catalyst Switches. however if I want to check to
PortBased Multi-Auth , MAC address Auth and any certification Auth with this feature,
Is it possible to integrate into Cisco Router such as Cisco 891F ?
In my opinion Cisco891F is also available to use basic IEEE802.1x but if it compares with Catalyst switches such as Cat3560X
I think there might be any unsupported feature on Cisco 891F.
I appreciate any information. thank you very much in advance.

Many time in interviews asked comaprison between cisco routers and switches that i was answerless bcoz i dont have much knowledge about that.Can anyone provide me the compariosin sheet of the same.how are the cisco devices differ with each other how much Bandwidth each routres support and Etc...
Ummmm ... The most common question I get is "what is the difference between a router and a switch".
However, if you get a question like this, then my impression to this line of questioning are:
1. The candidate they are looking for has in-depth knowledge of routers and switches. And I mean IN-DEPTH!;
2. They are not looking for a candidate. They just want to stroke their ego. There is not alot of people who can give you the "names and numbers" of routers and switches at a snap of a finger. And if you do happen to know the answer, then and there, then expect a tougher follow-up question.

Wireless connection lost between my router and printer (hp officejet 4620)

My hp officejet 4620 printer has been working fine but now the wireless connection has been lost and I can't get the wireless connection back. The blue light for the wifi flashes blue. I can't get the connection back between the router and the printer because my wifi is actually working fine with my laptop. Any suggestions about what i can do to get the connection back so I can print again?
Is it something I need to do on the printer screen or laptop to fix the problem?

Have you powered off everything and power up again? Power off printer and router. Power on router and wait 2 mins. Power up printer and see if it connects to your SSID.

What's the difference between transport route and transport layer

what's the difference between transport route and transport layer,Can somebody give me some explaination? thks in advance!

Hi,
Transport Layer in ABAP Workbench
    The Change and Transport System supports the distribution of development
    work on large projects across multiple SAP Systems.
    The packages in each development system are grouped into one transport
    layer.
    The transport layer determines whether objects are assigned to a local
    or transportable change request.
Use
    Each of your SAP development systems is assigned a transport layer as
    its standard transport layer. If you use Extended Transport Control, you
    can assign different standard transport layers to certain clients.
    You can define at the most one consolidation target for each SAP System
and transport layer.
When you create a package, it is assigned the standard transport layer
of the SAP System.
If you want to assign a different transport layer to a package, you
require the administration authorization for the Change and Transport
System.
The objects in a package automatically have the transport attributes
defined for the corresponding transport layer.
o   If a consolidation route originating in their SAP System is defined,
     then the objects are assigned to a transportable request, and
     transported into the consolidation target when it is released.
o   If a consolidation route is not defined, the objects are assigned to
     a local request, and are not transported.
Customizing settings are not assigned to a package. They have the
transport attributes of the standard transport layer of the system or
client.
It is best to assign a package a standard transport layer for which a
consolidation route originating in the development system is defined.
To display and maintain the transport layers and routes, use the
Transport Management System (transaction STMS).
Only the system adminstrator can make changes.
Caution:
     The tables TSYST, DEVL, TWSYS, TASYS are no longer productive as of
     Release 4.0A and cannot be maintained.

Sip trunk between CUCM7.0 and third party VOIP provider

Hi all,
I'm looking for a solution/howto configuration for setting up a SIP trunk between CUCM7.0 and a SIP-VoIP provider.
Got SIP username, password and SIP-proxy IP from the provider.
I've done such a setup on CUCME a couple of times, but never on the CUCM.
Who can put me on right way?
Can it be done on the CUCM, or must an IOS-Device be used (got a PSTN-GW connected through H323 with CUCM)?
THanks for the hint,

Differences between rate routing and reference rate routings?

Hello PP members:
I would like to differences between rate routing and reference rate routings
Thanks for your time,
Thanks Again,
Suren R

Hi Mr.Suren,
As explained by other friends Routing is used in Discrete manufacturing and Rate routing is used for REM-Repetitive manufacturing.
In addional to these types SAP has given 2 more types
1.Reference operation set -Used in Discrete manufacturing.
2.Reference rate routing - Used in REM.
If similar rate routing is been used for producing many materials,then instead of entering(these steps) in rate routing of each material you create a refrence rate routing and you enter the work centres used and the other details.After saving you get a group counter number showing reference rate routing is saved with group XXXXXXXXX.
When you are creating rate routing for a material say A ,after giving the name and plant details in the top you will be able to see an icon "copy from" and you can select the radio button for reference rate routing and give the group counter number. or else without giving it here you have got an option to select the reference rate routing after entering into the operation screen also.
In that particular page in operation overview screen,there will be an icon copy,there you can click that icon and you can give the reference rate routing group counter number and very easily you can create rate routing for N number of material.
Likewise you can use reference operation set while creating routing for a material in Discrete manufacturing.This basically reduces the time in creating routing or rate routing for materials in Discrete & REM respectively
CA01,CA02,CA03-Create,Change,display (routing) respectively.
CA11,CA12,CA13-Create,Change,Display reference operation set Respectively.
CA21,CA22,CA23-Create,Change,Display rate routing respectively.
CA31,CA32,CA33-create,change,display reference rate routing resp.
I hope this will help you.
If useful reward your points.
Thanks & regards
Karthik.

Principal difference between an Idoc and a Switch document.

Hello
what is the principal difference between an Idoc and a Switch document.
Thanks

Hi,
A switch document documents a process, such as, switch of supplier, in a liberalized market and can be monitored with own transactions. The process steps are usually controlled by workflows.
An IDoc is used to transfer data from one system to another one in a predefined package. When you import an IDoc containing a market message, a workflow can be started creating/updating switch documents.
Kind regards,

3640 router and 2950 switch via fiber

hi all,
is it possible to get a 3640 router with a NM-1FE-FX(100basefx) module and a WS-C2950C-24(100basefx) switch and setup 802.1q between them??
TX

If you wan to trunk between them then the answer is yes you can trunk between as long as the router has a newer version of code on it like 12.2

Trunking between Huawei S3900 and Cisco catalyst 3750

One of my edge Huawei S3700 switches is dead, I am going to replace it with a Cisco switch Catalyst 3750 series PoE-48 via a trunk link with GE fiber port on both ends, please see the diagram below.
trunk trunk
Core switchrouter<----------S3700<--------------->Cisco Catlyst 3750
I haven’t touch Cisco switch for many years, I would like to ask the following questions:
1.)      Do I need to take any precaution before connecting this Cisco switch into my Huawei network? Only one link between S3700 and C3750, so I don't need worry anout STP? Do I need to worry about Default vlan regarding trunking port?
2.)      I need to use different trucking protocol e.g. 802.1Q etc to interconnect these two switches (S3700-28TP-SI-AC and Catalyst 3750), please see the following configuration:
For C3750:
switchport trunk encapsulation dot1q
switchport trunk native vlan (What you want)
switchport trunk allowed vlan (VLANs required)
switchport mode trunk
spanning-tree portfast trunk
For S3700:
port link-type trunk
port trunk permit vlan all
Do you think the configurations above are right?
Do I need to manually enter Duplex and speed options ?
3.)If the configurations are not right, then what are the commands for trucking port/link should I use on the Cisco switch (it uses IOS software) and Huawei switch? Procedures of the commands would be really helpful !
Any information and help would be much appreciated.
Thanks
Regards

Hello
3750 - basic config
================
See as you are using this switch as an host switch you need to make sure ip routing isn't enabled ( it isn't by default)
Also it looks like the s3700 Huawei switch is permitting all vlans and I assuming the default native vlan is 1 ( as is cisco) so no need to specify the native either.
If you are requiring the access ports on this new cisco 3750 to be in multiple vlans then usually cisco to cisco interconnect would ultise VTP for vlan propagation however this wont occur between the Huawei switch, so you will need to manually add the vlans on the switch also.
so to summarize below is a basic host switch config for 3750.

Dot1q Trunk between Catalyst 6500 and HP Blade Enclosures

We have a requirement to configure trunks to a 6500 and HP GbE2 interconnect switch in a blade enclosure.
The interconnect switches and the 6500 are connected as in the attachment.
The configuration was done using the documentation provided by HP for connecting these trunks to the 6500, but there seems to be some problem with STP.
All the network remains stable for a time and then falls over, traffic counts on the trunk interfaces shoots up to crazy values.
The access layer (consisting of 2950s) hanging off the 6500 also falls over and the interfaces on the trunks become err-disabled. This happens eventhough we are not trunking the 102-108 vlans that are trunked to the HP switches to these switches.
We need to run dot1q trunks to the HP blade switches, because of the requirement to have the servers within the blade enclosure in different VLANS. The vlans were configured as per the document provided by HP and the server ports assigned accordingly.
Has anyone managed to configure etherchannel trunks (dot1q) to HP blade switches? Any guidelines and findings will help

Port Forwarding not working between Fios Router and Netgear R6200 AT ALL

For the past two days I've been trying to forward port 80 and port 9000 from my Fios Router to my new NetGear R6200 Router and absolutely nothing is working. I need these ports open and forwarded as I need to forward them to my surveillance system from my R6200. The problem is that port forwarding is not working AT ALL. I've literally tried EVERYTHING. I turned my firewall off completely, enabled DMZ, changed my R6200 to a static IP, turned off uPnP on both sides, and reset my router to factory settings. I'm all out of patience and ideas. This is exactly why I went out and bought the R6200 in the first place, Verizon's Routers are atrocious.
Hardware:
First Router (Gateway): Verizon Fios Aciontec MI424WR
Second Router: NetGear R6200 Dual Band 802.11AC Router
Surveillance System DVR: Zmodo H9114 DVR
OS: Windows 8 Pro 64-Bit
At this point I'm willing to try anything. Fios customer support knew absolutely nothing and wasted my time and if a tech is sent to my house I'm sure the same exact outcome will occur. I recall someone saying that cloning the MAC of a different REV. worked for them but I don't recall the details. Any help would be greatly appreciated.

#1 As addressed in http://www.dslreports.com/faq/12506
The DHCP Server in the secondary router should be off.
#2 You only forward from the main router directly to the computer that you want to host on.

VLAN with 1700 router and Linksys switch

I am trying to use a 1700 router to route between to IP subnets on two different VLANs setup on a Linksys switch. I do not have access to the switch so I am working with another tech that handles the switch. I setup two subinterfaces on the FE port of the router. Int Fa0.1 uses IP 1.1.1.1 and VLAN 1 native using 802.1q. Int Fa0.2 uses IP 2.2.2.2 and VLAN 2. I asked the switch tech to setup his switch accordingly. My problem right now is that the router will only ping IPs on the native VLAN. Meaning if I make Fa0.1 VLAN 1 native I can ping devices on 1.1.1.0/24 and if I make Fa0.2 VLAN 2 native then I can ping on 2.2.2.0/24. When I passed this along to the tech he explains something about setting up his ports for tagged or untagged but I don't know who this would apply to the router but he doesn't have a solution either. Is there anythin I can do on the router side to fix this?
Thanks,
Diego

hi,
I've tried connecting cisco to non cisco devices.Tagged ports simply means allowing different vlan to pass to that port and Untagged is passing only the native vlan.For your case since you want that two VLAN will communicate,port should be tagged.Tagged is simply trunking in terms to cisco.So that the 802.1q frames will pass that port.

Vlan routing with cisco router and linksys switch

I have a linksys switch width vlan configured, connected to a Cisco router (1841), but I cant route between vlans.
Please help me!!
It Works with a Cisco switch perfectly(with the same ip and vlan).

Yes. the linksys switch (SRW2024 24-Port 10/100/1000 Gigabit Switch) supports trunking.
If you want you can visit the link and see that the switch supports vlan, dot1q and trunking.

3750 as a router and a switch. sub-optimal routing problem

Objective: To limit the traffic on Vlan8. We are seeing traces from K1 or T1 to 192.168.1.4 like this:
1- 10.10.10.5
2- 10.10.20.1
3- 192.168.1.4
then
1- 10.10.10.4
2- 10.10.30.1
3- 192.168.1.4
or
1- 10.10.10.5
2- 10.10.200.1
3- 192.168.1.4
this causes the packets to travers vlan8 once to get routed by P61B then switched back across to reach the next hop 20.1 or vice versa.
How can we avoid this behavior?
Study the attached drawing carefully. Vlan 8 has 4 routers on it and the 3750s have routes to the 4 networks above them. packets are not routed between the 3750's

Hello Todd,
Could set up a debug ip icmp on the router 192.168.1.4 and ping it from both T-1 and K-1, I think this problem would be more clear to everyone.
If not mabybe you could provide the output of "show ip route" on the routes on this issue,at least on the routers/switch 192.168.1.2 , 192.168.1.3 and 10.10.10.4 and 10.10.10.5 and T-1, K-1.
for routes like 192.168.1.4, 10.10.10.2-5 and 20.20.20.2-3
Hope thats not to much info.
Thanks,
Vlad
