100BaseFX and Cisco Catalyst 3750G

Hi,
I need some help, I have a factory plant running some IE 3000 and Rockwell Stratix 8000 with GLC-FE-100FX-RGD transceiver to some older switches I need to replace the idea is to use Cisco 3750G, I saw in the Cisco 3750G datasheet a GLC-GE-100FX= transceiver would they work together point-to-point? what sort of connector do they use are they LC also?
The idea is to use 100BaseFX MM because of the costs, distance (800M) and the bandwith being light.
Thank You

The GLC-GE-100FX= and the GLC-FE-100FX-RGD SFPs have the same optical performance specifications, so they will interoperate across a link. The RGD SFP has a higher operating temperature range for industrial applications (per data sheet), where the IE 3000 is typically installed.
Hope this helps!

Upgrade of Cisco Catalyst 3750G 24T

Hi,
I want to upgarde a Cisco Catalyst 3750G 24T because I can't see the web interface.
I checked the documentation and see a lot of videos on the net.
I downloaded the new firmware c3750-ipbasek9-mz.122-55.SE9.bin
I downloaded a tftp software and putted my ip adress on it.
I connected the Cisco by console and launched Putty by serial.
I sended en for grant my right access.
I sended my password
and tapped :
copy tftp: flash:
it asks TFTP Ip, i gave it
10.0.0.45
file name
i gave it
c3750-ipbasek9-mz.122-55.SE9.bin
and after It sended me when it must put it and i sended the same name.
c3750-ipbasek9-mz.122-55.SE9.bin
And then It works few seconds and the cisco says error ... time out.
I've tested with W8, W7 and a lot of tftp server. I disabled my firewall.
The password is the default password. It is a problem ?
Can you help me ?
Thanks
Nicolas

Copying only the BIN files into the appliance will NOT help. You still won't be able to use the web interface.
You need to download the full IOS, the filename ends with TAR. To unpack the file into your appliance you use the command "archive download-sw tftp://<TFTP IP address>/filename.tar".

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:

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

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.
conf t

RPS and Cisco Catalyst 2950 and 3550 switches

We are doing experiments with RPS and CC 2950 and 3550. When we unplug the main power, the RPS takes over and feeds the switch with power. But when we plug the main power back again, the switch contiues to take power from the RPS. How is the power reduncancy achieved with CC 2950 and/or 3550s?
Thanks in advance,
Dardan

You will need to press the active/standby button on the RPS for the internal power supply in the switch to take over. Note that this can cause the switch to reload and do it in your maintenance window if this switch is in production.

MGBSX1 and Cisco catalyst 2960 24-PCL compatibilty

Hi,
I'd like to know if someone has a solution to install MGBSX1 with C2960-24-PC-L because I have to buy a lot of transceiver and the price of GLC-SX-MM is x5 the price of MGBSX1
thx

1) I believe 10/100 Ethernet uses 4 wires and 1000 Ethernet uses 8 wires. Will the uplink ports connect all 8 of its wires across the 10/100 ports?
Depends. If both uplink ports are 1Gig and you have a Cat5 cable with 2 pairs terminated (4 links) then the speed will only negotiate to 100mbps.
2) Can a 10/100 port connect to another switch using a crossover cable? If so, what happens if a 10/100 port is connected to a 1000 port? Would any damage to the switch occur? As long as you leave speed and duplex setting to auto and MDI/MDI-X will kick in automatically.

Communication problem between ASA 5510 and Cisco 3750, L2 Decode drops

Having problem with communication between ASA 5510 an Cisco Catalyst 3750.
Here is the Cisco switch port facing the ASA 5510 configuration:
interface FastEthernet2/0/6
description Trunk to ASA 5510
switchport trunk encapsulation dot1q
switchport trunk native vlan 50
switchport trunk allowed vlan 131,500
switchport mode trunk
switchport nonegotiate
And here is the ASA 5510 port configuration:
interface Ethernet0/3
speed 100
no nameif
no security-level
no ip address
interface Ethernet0/3.500
vlan 500
nameif outside
security-level 0
ip address X.X.X.69 255.255.255.0
There is a default route on ASA to X.X.X.1.
When I try to ping from ASA X.X.X.1 i get:
Sending 5, 100-byte ICMP Echos to 31.24.36.1, timeout is 2 seconds:
Also in the output of show interface eth 0/3 on the ASA i can see that the L2 Decode drop counter increases.
I have also changed the ports on the Switch and ASA but the same error stays.
Any thoughts?

I don't see anything wrong with your trunk configuration; I have a similar one working between an ASA 5520 and a Catalyst 3750G.
Maybe you should adjust the "speed 100"? In my experience, partial autoconfiguration results in duplex mis-matches, which results in dropped packets.
I'd try removing the "speed 100" and letting the ASA port autonegotiate with the switch. Alternatively, have both sides set
speed 100
duplex full
and see if things improve.

Cisco Catalyst 2950/2960/3750 Multicast Traffic Preference

Hello all,
we, as a student company act as an ISP for university dormitories. We would like to (if it's possible) deploy QoS to prefer multicast traffic over all other types of traffic.
Devices used in network:
Acces layer: Cisco Catalyst 2950, 12.1(22)EA14
Dristribution layer: Cisco Catalyst 2960G, 12.2(58)SE1
Core layer: Cisco Catalyst 3750G, 12.2(52)SE
Do you see any possibility to solve this with these devices? We have almost no experience with QoS, therefore any help would be greatly appreciated.
Thanks in advance.

Hmm, I think it should be doable although the 2950s, if non-E variants, are especially weak in QoS features. I.e. those might create some issues.
With the 2960G and 3750G, you often will create problems when you enable QoS because QoS, by default, allocates its buffers resources for 4 egress queues per port rather than using all for 1 egress queue per port. However, this can be countered by QoS parameter tuning, but that takes some QoS expertize to match to your traffic and your overall QoS policy.

Cisco Catalyst 4500X

I want to buy Cisco Catalyst 4500-X-16SFP+ and upgrade the license to Enterprise service. But license description show "IP Base to Ent. Services license for 16 Port Catalyst 4500-X". Is it means that only 16 port is Enterprise Service? If I add more 8 Ports module ,can it use Ent Service?
Please kindly advise.
Thanks,
Mano

Is it means that only 16 port is Enterprise Service?
The license is in blocks of 16- or 32 ports. Let's say you purchase an Enterprise license for 16-ports and you got an optional 8-port module. You purchase an additional license of "C4500X-16P-IP-ES" and this allows you an additional 16-ports of license. You can't purchase a license for only 8 ports.

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 3750x and 4510R and Cisco Security Manager

Hi,
I just downloaded and install trial (evaluation) version of Cisco Security Manager 4.3. In supported devices list I saw Cisco Catalyst 3750 and 4510R but when I try to add it I got for 3750:
Invalid device: Device is a switch and cannot be mapped to a Generic Router model.
Please verify the selected device type, OS version and device configuration
For 4510R:
Invalid device: Version 03.03.00.SG (N/A) is not supported for the device type of Cisco Catalyst 4510R Switch Please verify the selected device type, OS version and device configuration
We need to make a purchase decision but for it we need to import all of our devices and perform some tests.
Thanks in advance for your replies!
BR, Vasily.

I figured this out on my own -- change Compatibility mode of the installer to be Windows 8 (which is same OS version as Windows 2012) and it installs just fine.

Cisco Catalyst WS-C3560-48TS and DLINK 3120 interface errors

Hello,
We are getting a lot of FCS-Err in one FC- GIgabit trunking interface between Cisco Catalyst WS-C3560-48TS running IOS Version 12.2(25)SEE3 and DLINK 3120 Firmware 4.00.015.
Our config in the cisco is the following:
interface GigabitEthernet0/1
description SWITCH-Dlink01
switchport trunk encapsulation dot1q
switchport mode trunk
macro description cisco-switch
spanning-tree link-type point-to-point
We have tried without "macro description cisco-switch" and "spanning-tree link-type point-to-point" too and the problem persist.
If we run "sh interfaces counters errors"
Port Align-Err FCS-Err Xmit-Err Rcv-Err UnderSize
Gi0/1 0 11423 0 11423 12516029
The errors counters in the DLINK are growing very fast too.
Usually these errors are related with hardware or cable problems, we have changed the cable, the SFP and the port, but the problem is still there.
We have activated the debug for the interface and syslog, but we aren't getting any error.
Do you have any idea about this issue or how to troubleshoot it?

Hi,
Try to hard set the ports on both sides to Gig/full duplex and test again.

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
