3750 Metro series do not dot1q trunking??

Folks,
I have a 3750 metro series switch and i am trying to use it to do inter vlan routing. I do not see an option for "encapsulation dot1q" under sub interface?? why is it not supported??
Thanks

Navin,
The 3750 Metro series switch does not support Layer 3 trunks; you cannot configure subinterfaces or use the encapsulation keyword on Layer 3 interfaces. The switch does support Layer 2 trunks and Layer 3 VLAN interfaces, which provide equivalent capabilities.
For more information, see the note under Table 12-5 on this page: http://www.cisco.com/en/US/products/hw/switches/ps5532/products_configuration_guide_chapter09186a00803960dc.html#wp1326724.
Cheers,

Narvin,
if you want inter-vlan routing, the interface Vlan nn itself specify vlan.I think you confuse with router subinterface where you must specify what Vlan a subinterface must use ( and encaps type ). Encaps type ( dot1q or ISL ) is used at trunk level, and whatever trunk use you can do intervlan routing using vlan interface.

Netflow on Cisco Catalyst 3750 Metro Series Switches

Does netflow possible in 3750 metro series?

Hi Syed,
You have to first check if there is any image in switch or not so that you can manually boot from switch: prompt but as you said there is no image in the switch you have to go for xmodem procedure to upgrade the switch.
Have a look at this link and just follow step by step instructions and you will be good to go

Hi Josh,
The Cisco Catalyst 3750 Metro Series is built for Metro Ethernet access in a customer location, enabling the delivery of more differentiated Metro Ethernet services. These switches feature bidirectional hierarchical QoS and Traffic Shaping, intelligent 802.1Q tunneling with class-of-service (CoS) mutation, VLAN translation, MPLS, EoMPLS, and Hierarchical Virtual Private LAN Service (H-VPLS) support, and redundant AC or DC power. They are ideal for service providers seeking to deliver profitable business services, such as Layer 2, Layer 3, and MPLS VPNs, in a variety of bandwidths and with different SLAs.
The metro switches have the PXF chips (which allow hierarchical QoS on the 2 "WAN" GigE ports, so several logical links can share a connection, and have soft bandwidth limits).
For more details on 3750-M switches have a look at this link

3750 Metro ethernet switch

Folks,
I have 6500's at the core and want to use the 3750 at the PE. My question is the following:
1) 3750 would do Q-IN-Q.
2) Once the packet reaches the 6500(sup 720) running MPLS. What happens to the frame. Do i use xconnect to transfer the frame to the appropriate PE?
Just confussed about how does the PE use the Q-IN-Q information to direct it to the appropriate PE?
Sample config would be highly appreciated.
Thanks

3750 Metro hardware defection.

When two 3750ME ,same IOS and same configuration, connected using fastethernet trunk, vlan interface over the trunk can't building ospf neighbor,one can recieve the ospf hello ,the other can't.We have 22 3750ME running in our network, several sites have met the same problem.
Futhermore ,when 3750 Metro connect with a 7507 router using a fast ethernet trunk, the 7507 interface configured dot1q,then the 3750ME interface lost packets.

Take care when setting the mode to on (manual configuration) in etherchannel PAgP modes. All ports configured in the on mode are bundled in the same group and are forced to have similar characteristics. If the group is misconfigured, packet loss or spanning-tree loops might occur.

Vlan 1 on dot1q trunks, cross-vtp-domain

Hello all,
trying to transport vlan 1 via .1Q between a c6500 (IOS) and a c35xx. The idea is to access the c35xx for management purposes.
Vlan 1 does not seem to work; neither the c35xx nor any devices attached to it can be seen in the vlan 1 cloud.
The 2 catalysts are members of different vtp domains. Both domains do include their vlan 1 definitions.
Any ideas?

When using dot1q trunking you must specify what the native vlan is on BOTH sides of the trunk if it is different from 1. If you want the Interface VLAN1 on your 3750 be accessible then it must be in the same network as VLAN1 on your 6509. If you have a different vlan on your 3750 for users but want to keep VLAN1 for management this is how you need to set it up: Using VLAN 25 for users and VLAN 1 for management Example below using GiX/Y for uplink interface to 3750:
interface Vlan25
ip address 172.30.25.2 255.255.255.0
ip helper-address 172.30.X.Y
no ip redirects
standby 1 priority 110 preempt
standby 1 ip 172.30.25.1
no shutdown
Interface GiX/Y
switchport
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1,25
switchport mode trunk
no shutdown
On 3750:
interface VLAN1
decription "Management Interface"
ip address 172.30.25.5 255.255.255.0
interface GigabitEthernet1/0/1
description "Trunk to 6509"
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1,25
switchport mode dynamic desirable
By NOT including: "switchport trunk native vlan 25"
on both sides of the trunk you are making VLAN 1 the native VLAN but still allowing VLAN 25 traffic

EoMPLS with Catalyst 3750 Metro Switches

Hi,
I am trying to setup an EoMPLS tunnel (VLAN mode) between two 3750 Metro switches. But I am not getting the Status down from the both PEs.Also the 'show mpls l2transport binding' shows no output interface and no label stack is attached. Can anybody in the forum help me out? Is it any IOS related problem.
The IOS version is:c3750me-i5k91-mz.122-25.SEG1.bin
Thank you,

Hi,
can you provide the related config? Without this it is hard to tell anything.

802.1Q Trunk Configuration Guidelines and Restrictions
The following configuration guidelines and restrictions apply when using 802.1Q trunks and impose some limitations on the trunking strategy for a network:
When connecting Cisco switches through an 802.1Q trunk, make sure that the native VLAN for an 802.1Q trunk is the same on both ends of the trunk link. If the native VLAN on one end of the trunk is different from the native VLAN on the other end, spanning-tree loops might result.
Disabling spanning tree on the native VLAN of an 802.1Q trunk without disabling spanning tree on every VLAN in the network can cause spanning-tree loops. We recommend that you leave spanning tree enabled on the native VLAN of an 802.1Q trunk. If this is not possible, disable spanning tree on every VLAN in the network. Make sure that your network is free of physical loops before disabling spanning tree.
When you connect two Cisco switches through 802.1Q trunks, the switches exchange spanning-tree BPDUs on each VLAN that is allowed on the trunks. The BPDUs on the native VLAN of the trunk are sent untagged to the reserved IEEE 802.1D spanning-tree multicast MAC address (01-80-C2-00-00-00). The BPDUs on all other VLANs on the trunk are sent tagged to the reserved Cisco Shared Spanning Tree (SSTP) multicast MAC address (01-00-0c-cc-cc-cd).
Non-Cisco 802.1Q switches maintain only a single instance of spanning tree (the Mono Spanning Tree, or MST) that defines the spanning-tree topology for all VLANs. When you connect a Cisco switch to a non-Cisco switch through an 802.1Q trunk, the MST of the non-Cisco switch and the native VLAN spanning tree of the Cisco switch combine to form a single spanning-tree topology known as the Common Spanning Tree (CST).
When you connect a Cisco switch to a non-Cisco switch, the CST is always on VLAN 1. The Cisco switch sends an untagged IEEE BDPU (01-80-C2-00-00-00) on VLAN 1 for the CST. On the native VLAN, the Cisco switch sends an untagged Cisco BPDU (01-00-0C-CC-CC-CC) which the non-Cisco switch forwards but does not act on (the IEEE BPDU is not forwarded on the native VLAN).
Because Cisco switches transmit BPDUs to the SSTP multicast MAC address on VLANs other than the native VLAN of the trunk, non-Cisco switches do not recognize these frames as BPDUs and flood them on all ports in the corresponding VLAN. Other Cisco switches that are connected to the non-Cisco 802.1Q cloud receive these flooded BPDUs. This situation allows Cisco switches to maintain a per-VLAN spanning-tree topology across a cloud of non-Cisco 802.1Q switches. The non-Cisco 802.1Q cloud separating the Cisco switches is treated as a single broadcast segment between all switches that are connected to the non-Cisco 802.1Q cloud through the 802.1Q trunks.
Make sure that the native VLAN is the same on all of the 802.1Q trunks connecting the Cisco switches to the non-Cisco 802.1Q cloud.
If you are connecting multiple Cisco switches to a non-Cisco 802.1Q cloud, all of the connections must be through 802.1Q trunks. You cannot connect Cisco switches to a non-Cisco 802.1Q cloud through ISL trunks or through access ports because the switch will place the ISL trunk port or access port into the spanning tree "port inconsistent" state and no traffic will pass through the port.

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

Forgot the attachment....

My hp deskjet 1510 series does not print when connected to my hplap top (windows Vista),

My hp deskjet 1510 series does not print when connected to my hp lap top (windows Vista), it says the printer is not active, although it is default printer, connected and on. However, it does work when connected to the (also HP) lap top (windows 8) of my husband. I did everything the hp print and scan doctor advised and also what I could find at HP support (like switch of fire walls, reinstall everything, check printpooler ec etc)... it still does nothing except that I managed to print a diagnostic print which should give information about the condition, but it only gives numbers and letters like : 11. SN = [Edited for Personal Information] Yr 12 PER = 05YR etc, that does not really help me :-). It won't print any testpages. H E L P!!!

Hello Elisabeeth,
Welcome to the HP Forums!
I understand you're unable to print using the Deskjet 1510. I will do my best to assist you! When you reinstall the HP software, did the installation state it was complete?
I would start off by following this HP document on 'Printer is offline' Message Displays on the Computer and the Printer Will Not Print. From this document, please make sure you check the connection type and the ports.
Please post your results, as I will be looking forward to hearing from you.
I worked on behalf of HP.

Our new wireless printer will not scan. I have tried to scan from the computer and get the below error message and then I have activated the scan from printer and when I push the scan button on the printer, I get the same error message.
Thanks!

I had some problem. I found you must use HP 'Update IP address' program to add printer instead use window add printer. All programs -> HP ->HP Deskjet 3050 610 series -> Update IP address.
