VLAN trunking from Cisco Catalyst 3750 to Cisco SF300-48P issue and related

Hello expert,
I'm having difficulties to configure VLAN trunking between Cisco Catalyst 3750 switch with Cisco SF300-48P switch and my workstation unable to get any DHCP IP from our DHCP server via Cisco SF300-48P switch. Below is the snippet of configuration on both switches:
[Cisco Catalyst 3750 Switch]
interface GigabitEthernet1/0/45
description NCC-CC-1stFlr
no switchport trunk encapsulation dot1q
no switchport trunk allowed vlan 101-103
spanning-tree portfast
[Cisco SF300-48P Switch]
interface fastethernet48
spanning-tree link-type point-to-point
switchport trunk allowed vlan add 101-103
macro description switch
!next command is internal.
macro auto smartport dynamic_type switch
interface fastethernet29
switchport mode general
switchport general allowed vlan add 103 tagged
switchport general pvid 103
Are these are correct? Kindly advice!
Thank you very much!
Regards,
Alex

Hi Alex,
for the trunk port on Catalyst on port GE 1/0/45, we need to enable the trunk and for on encapsulation dot1q because this catalyst model is ISL capable also and the SF300 working only with Dot1q Encapsultion
The configuration on catalyst should :
#config terminal
#interface Gi 1/0/45
# switchport encapsulation
#switchport trunk encapsulation dot1q
#switchport mode trunk
#switchport trunk allowed vlan 101-103
#spanning-tree portfast
For SF300 the port trunk it looks fine but for the port where the PC should receive an IP address
#interface fastethernet29
#switchport mode access
#switchport ccess vlan 103
Please let me know after this configuration
Thanks

Debian Linux Bonding and Cisco Catalyst 3750 - best practise?

Hello everybody,
I would like to know what's best practice to do this:
The two NICs of a Debian Linux server wants to be connected with two Switchports of a Cisco Catalyst 3750 switch(stack). My goal is to have load-balancing and failover.
My /etc/network/interfaces looks like this:
iface bond0 inet static
       address 192.168.0.30
       netmask 255.255.255.0
       network 192.168.0.0
       broadcast 192.168.0.255
       gateway 192.168.0.1
       dns-nameservers 192.168.0.10 192.168.0.20
       dns-search xyz.mycompany.com
       slaves eth0 eth1
       bond_mode ???
       bond_miimon 100
       bond_downdelay 200
       bond-updelay 200
First question: What bond mode should I use?
The switchports looks like this:
interface GigabitEthernet3/0/4
switchport access vlan 20
switchport mode access
spanning-tree portfast
What changes are necessery here? Something like this?
interface GigabitEthernet3/0/4
switchport trunk encapsulation dot1q
switchport mode trunk
spanning-tree portfast
Thanks a lot for suggestions, hints, etc.! :-)

Hi Michael,
thanks a lot for your answer - and sorry for my late reply!
I like to show you my solution - I hope that it is a solution. ;-)
My config on the switch(stack):

end
The /etc/network/interfaces of my Debian machine looks like this:
auto lo
iface lo inet loopback
auto bond0
        iface bond0 inet static
        address 192.168.1.xxx
        netmask 255.255.255.0
        gateway 192.168.1.xxx
        dns-nameservers 192.168.1.xxx
        dns-search xxx.xxx.xxx
        bond-mode 4
        bond-miimon 100
        bond-downdelay 200
        bond-updelay 200
        bond-lacp-rate 1
        slaves eth0 eth1
This setup seems to work well. But I'm wondering that there is nothing with "trunking" in my setup. Would you like to give me your opinion about this?
Thanks a lot and many greets

I cannot connect by console port to Cisco Catalyst 3750 using ethernet to USB.

Hello. I have one Cisco Catalyst 3750 switch, and two 2950 switches. I am trying to reset their settings using a console cable with a trendnet Ethernet to USB adapter. When I try loading hyperterm or putty on com3 there is no signal. I have the communication port setting on com3. I don't know what the old settings are, and they can be reset. I get connectivity lights when plugging the cable into the switch ports. What am I missing?

Are you definitely using the correct COM Port number? On Windows7 Right Click My Computer > Manage Then select Device Manager and expanPorts (COM & LPT)d in my case is shows Prolific USB-to-Serial Comm Port (COM5).
Once you have the right COM Port number just use the default settings in Putty. You may find the COM Port is locked up which will require a reboot.

Cisco Catalyst 3750-X or 3560-X Series Switches

Recently, our company was deciding to buy Cisco switches, but they just tell the requirements and I finally focused on two kinds of switches, Cisco Catalyst
3750-X or 3560-XSeries Switches? Who can tell me, tnx in advance.

As I read a blog recently, it listed the specific differences between Cisco 3750-X and 3560-X, except for the common features of Cisco 3750-X and 3560-X, Cisco 3750-X can also offer-- Cisco StackPower technology: An innovative feature and industry first for sharing power among stack members;
Cisco StackWise Plus technology for ease of use and resiliency with 64 Gbps of throughput;
Investment protection with backward compatibility with all other models of Cisco Catalyst 3750 Series Switches.
And made a more detailed comparison between the two products, for ur reference.

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.

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

Cisco Catalyst 3750 & Linksys SGE2000P

Hello everyone,
I m in the process of addin new switches with Gigabit port in my server room, actually I have a single switch 48 port (a Cisco 3550) that is connected to a Core Switch via fibre channel but I need to migrate some of my server in a gigabit mode. My management did not allow me to buy a new Cisco switch, because the model with 24 port Gigabit is a bit expensive. so I need to find another solution.
My first thought was to buy a Linksys SGE2000P, and connect it to our Core switch via a fiber channel, to do that I must be sure that a SGE2000P is compatible with my Core switch (3750 12 port SFP) so here is my question does anyone around here has already tried that ? :-)
Thanks in advance
regards,
Arnaud Leresche

I think there should be no compatibility issue BUT I have not personally tried it.

VLAN trunk from switch to router

We have a 2691 cisco router and a Linksys (cisco) 24 port switch.
Each E port is set with a different untagged VLAN ID grouped to G1 uplink port and is tagged
The G1 port then is trunked and is tagged to native VLan 1
One of the router ethernet ports is configued as
interface FastEthernet0/0
description $ETH-LAN$
no ip address
ip flow ingress
duplex auto
speed auto
no cdp enable
interface FastEthernet0/0.1
description $ETH-LAN$
encapsulation dot1Q 1 native
ip address 216.110.213.1 255.255.255.0
ip flow ingress
no snmp trap link-status
no cdp enable
Is this correct ?
Problem is all VLAN E ports on switch cannot get past the router.
Some E ports not with VLAN then default to VLAN 1 and they can function past the router.
The config of the switch was verified with Linksys as being correct which leaves a router config issue
So in short the switch would have 24 VLANs untagged going through trunk which is tagged ending up hitting router and then out WAN ports.
Thanks for any help for cisco and linksys have been no help solving why servers on switch with vlan cannot see past router
JR

Is this correct ?
A: The configuration above says that vlan 1 is native vlan, which means the router is expecting a "raw" packet to belong to vlan 1. "raw" packet menas it does not have any vlan id, I do not want to use "tag" coz "tag" might mean something else to Linksys. So, if it's "raw" as in if a PC transmit a packet, it will have no vlan id field.
Problem is all VLAN E ports on switch cannot get past the router.
Some E ports not with VLAN then default to VLAN 1 and they can function past the router.
A: If you mean, they can ping the 216.110.213.1 and beyond 216.110.213.0/24 then that would be expected.
The ports that belongs to other vlans will need a default gateway of their own, they cannot use the vlan 1 gateway because they are in different subnet. from the cofnig above, you only have sub-interface for vlan 1, do you have sub-interface for other vlans? If not, you need it.
The config of the switch was verified with Linksys as being correct which leaves a router config issue
So in short the switch would have 24 VLANs untagged going through trunk which is tagged ending up hitting router and then out WAN ports.
>> This goes back to above, native vlan on cisco router will be the only vlan the router will expect with no vlan id, otherwise, everything the router rx with no vlan id or dot1q encapsulation will be assumed that it belongs to vlan 1. do you have other sub-interfaces on the 2691 for the other 24 vlans?

Alternative switch to Cisco Catalyst 3750v2-24FS and 3750-24FS

I`m looking for an alternative to these two switches:
1. WS-C3750V2-24FS-S Cisco Catalyst 3750V2-24FS Switch with 24 100FX SFP + 2 Gigabit Ethernet SFP Ports
2. Cisco Catalyst 3750-24FS (WS-C3750-24FS-S 100BASE-FX)
They are now EOL and not available.
I have a campus style network and need to be able to connect multiple 100FX fibre switches back to a central switch. The 1st unit uses 100FX SFP modules and the second has in-built 100FX ports. I`m struggling to find anything from Cisco that will give me multiple (i.e 12+) 100FX ports.
Could anyone please point me in the right direction?
Many thanks,
Paul

Hi Paul ,
Replacement for both switch is WS-C3650-48TS-S.

Catalyst 3750 Ingress SPQ/SRR behavior

Do Cisco engineers review this community at all?
I am working on the latest version of QoS standard for our Enterprise and noticed the following conflicting information officially provided by Cisco.
My question relates to ingress/pre-ring Strict Priority Queue (SPQ) logic.
Cisco Catalyst 3750 QoS Configuration Examples document states that SPQ on ingress is configured and serviced as follows
mls qos srr-queue input priority-queue 2 bandwidth 10
mls qos srr-queue input bandwidth 90 10
SPQ services Q2 up to the configured 10% of ingress bandwidth
Any excessive traffic in Q2 is not dropped, but is serviced by SRR in accordance with the configured weights
For example, a momentary 5Gbps of aggregated ingress EF traffic will be serviced in the following way
SQP services 10% of total ring's bandwidth, or 3.2Gbp, leaving 1.8Gbps for SRR processing
SRR services excessive 1.8Gbps in accordance w/ weights Q1 - 90 and Q2 - 10, such as Q1 gets 25.92Gbps and Q2 get 2.88Gbps more.
The following pictures provides in-depth look into Ingress queuing logic.
Alternatively, Cisco Medianet Campus Design v4.0 provides the following example w/ comments
C3750-E(config)#mls qos srr-queue input priority-queue 2 bandwidth 30
! Q2 is enabled as a strict-priority ingress queue with 30% BW
C3750-E(config)#mls qos srr-queue input bandwidth 70 30
! Q1 is assigned 70% BW via SRR shared weights
! Q2 SRR shared weight is ignored (as it has been configured as a PQ)
Basically, they now say Q2 bandwidth weight is ignore because it is configured as Strict Priority Queue. Doesn't it look contradictory?
In my humble opinion Medianet (or SRND v4.0!!!) provides an incorrect information re ingress queuing on Catalyst 3750 platform.
I am not sure I can easily test it, providing that an internal ring must experience a congestion. I don't think I can send more than 32Gbps of traffic into any of my lab 3750 switches.
Also, I don't think this mistake can be critical in my environment as I don't expect to have momentary full capacity load on those... but it can be critical for others.
Much appreciate
Tim

Catalyst 2960 - IBM/Cisco IGESM - Trunk port configuration

Good day all!
I am new in Cisco world and try to configure a trunk between a Catalyst 2960 switch and a IBM Blade Center IGESM switch (manifactured by Cisco).
Unfortunately, it seems that the network traffic doesn't cross the trunk link.
I have followed (at least, I think so) the instructions given on the different Cisco documentation papers but I can't find the mistake in my configuration (lack of experience :-( !).
Both switches are using IOS. 2960 uses IOS 12.2(25)FX and IGESM uses IOS 12.2(22)EA8.
The ports are connected through a cross-over cable Cat5e.
Please find below the configuration for each ports:

For my test, I try to ping a blade (connected to IGESM) in VLAN 200 from a workstation connected to Catalyst 2960 (in VLAN 200 too). From a network anaylser (ethereal), I can see the ARP broadcast from each side but none are going across the trunk link.
I am a bit lost about this problem and would be grateful for any assistance in solving it!
Many, many thanks in advance for your time!
Best regards,
Fabian

Hi Glen!
Both switches (Catalyst 2960 & IGESM) are brand new and most ports are still reflecting manufacturer's default configuration. Vlan 2 is the default native vlan for IGESM ports (excluding ports used for switch management which use vlan 1 as most Cisco switches).
I changed the native vlan for g0/5 on IGESM to 200. Now, ports g0/5 (access mode) and g0/20 (trunk mode) are on native vlan 200. On g0/5 is installed Windows 2003 instance (firewall disabled). The only purpose is to receive and send ping request to test connectivity.
My workstation is connected to 2960 switch on port fa0/1 (please find the configuration below). I can successfully ping other vlan 200 machines connected on the same switch. For testing purpose, I try to ping the blade machine connected on port g0/5 on IGESM.
Configuration of fa0/1:
Name: Fa0/1
Switchport: Enabled
Administrative Mode: dynamic auto
Operational Mode: static access
Administrative Trunking Encapsulation: dot1q
Operational Trunking Encapsulation: native
Negotiation of Trunking: On

Is there any other information I could provide to better help you to understand the configuration?
Cheers!
