Nexus 2K to Cisco 2960 IOS Switch
Hi,
I am trying to connect Nexus 2K FEX to Cisco 2960 IOS Switch (Trunk config) and causing spanning tree loop having issues. I am aware that I should't be connecting non host port to 2K FEX but it's corner case. I have done similar setup with Access Port configuration and didn't faced any issues.

Should I configure port as "spanning-tree port type network" and create VPC and "storm-control broadcast level" to stop future occurrence? OR Do i have to configure anything else to prevent spanning-tree loops?
Thanks for your help
RiteshHi,
spanning-tree port type network is used for VPC peer-link. Try creating a new VPC and add ports 107/1/47 and 108/1/47 to it and a Portchannel on the 2960 and test.

Hi all,
I have some problems involved Cisco Catalyst 2960 Switch.
I am using a device which includes Marvell PHY chip 88E1111. The device can send and receive PTP packet to and from my PC.
Now, I want to connect the device and the PC to Cisco Catalyst 2960 Switch, which will help me trace all of packets in the network . The test scenario is below:
- Switch: Cisco Catalyst 2960
- Tracer: Wireshark software
- PC: Windows 7-64 bit, plugging in Switch port 1 (interface 1)
- Device: FPGA board, plugging in Switch port 2 (interface 2),
operating mode: 1000Mbps, Fullduplex, no auto-negotiation, no auto power efficient-ethernet.
- Interface 2 of the Switch is static set by the device’s MAC
address , which ensures the Switch known the device’s MAC.
I suffered a problem. Although the RJ45 TX status led are on, there is not any packet sent to the Switch. I have no idea in this case.
Could you give me an advise please.It means the IOS used is corrupt.
Go to the Cisco website and download again the IOS. Once download is complete, compare the MD5 hash value of the file downloaded against the MD5 hash value found in the Cisco website. -

How to connet cisco 2960S switch to sony nexus 7?
I want to buy an cisco WS-C2960S-24TS-S switch to help me solve business networking problem. Can someone help me to connect cisco 2960s switch to nexus 7 ?
I don't need to do anything config on the new switch, I just need to upgrade the new switch's IOS version as the existing stack.
Correct. Upgrade using the command "archive download-sw" instead copying the BIN files.
After doing above task, I connect all stack cable and power cord as you said, and then the new switch can be synchronized with the MASTER switch. right??
Correct. The new switch should NOT have any configuration. This includes VLAN.dat file. -

Cisco 2960S-24TS-S using SFP modules between switches
I am using Cisco 2960S-24TS-S using SFP modules for two different speed requirements, I have two SFP ports using 100Mbit modules and the other two SFP ports using 1000Mbit modules.
I have two Cisco 2960S-24TS-S switches connected together via a fiber optic cable, and each SFP module is on port 28, with a 1000 Mbit SFP module in each, and the two switches will not connect. The fiber was checked with a light tester not a db kit.
Do I need to have SFP port specific setup details in a configuration file for the Cisco Switch or does the SFP module handle this?
" interface GigabitEthernet1/0/28" - set up in config file for the port. Does this need to dictate "interface 100" or "1000MbitEthernet1/0/28" instead?The ports should auto-negotiate speed you should not need to hard code them to get them to come up , Are the ports showing up/down or down/down can you post the show interface for each side and the show run int x/x for each port

Cisco 2960s Switch replacement
Greetings,
Dear Experts,
We are using the Cisco 2960s Switches in our network. We have two failed switches and asked for replacement from our supplier. They informed that the 2960s model is approaching End Of Service (EOS) and the replacement of that model are as below:
1- WS-C2960X-24TS-L
Catalyst 2960-X 24 GigE, 4 x 1G SFP, LAN Base
2-WS-C2960S-24TS-L
Catalyst 2960S 24 GigE, 4 x SFP LAN Base
What is the best practice to make my decision of which to select? will it make difference from the configuration perspective? is there a possibility for conflict with the existing 2960s Switches?
Many thanks in advance for your kind assistance.
Thanks and RegardsWe have two failed switches and asked for replacement from our supplier.
Time for you to talk to your supplier. Cisco has announced the EoS/EoL for the 2960S back in November 2014 (End-of-Sale and End-of-Life Announcement for the Cisco Catalyst 2960-S Series and 2960-SF Series Switches). However, this only means the date of November 2014 is just a date of announcement. The final date of sale for the 2960S is November 2015.
I think your supplier either is getting confused (didn't read the announcement properly or didn't know) or is just looking for ways to make more money.
is there a possibility for conflict with the existing 2960s Switches?
You can form a stack of 2960S and 2960X. Just know the limitations, and they are:
1. The entire stack must have the same IOS versions;
2. The stack speed will drop from 20 Gbps (2960X) to 10 Gbps because 2960S has been set to run only at this speed; and
3. You cannot have five or more in a stack if you have a 2960S as a member of the stack. -

Cisco 2960-X & ISE accounting- username Radius attribute missing
Hi,
I'm facing an issue with cisco 2960 switch radius accounting with Cisco ISE1.2.1 .here is my senario:
- Username (vendor1) is configured in ISE local database, under group (VENDOR)
- Authentication protocol : wired MAB
- Authentication method : webauth using guest portal , the user is a vendor , so no dot1x configured on his NIC .
the problem is that , the switch is not sending the username as a part of radius attribute , in the authentication log , the username shown as the MAC address of the user machine , therefor , I can not configure my authorization condition using internaluser:Name Equal vendor1
while if I configure the condition using the identity group condition IdentityGroup:Name Equal VENDOR , it works .
The same configuration is working on 3750 switch with no issue .
Here is my Switch config:
aaa authentication login default local
aaa authentication dot1x default group radius
aaa authorization network default group radius
aaa authorization auth-proxy default group radius
aaa accounting auth-proxy default start-stop group radius
aaa accounting dot1x default start-stop group radius
aaa accounting update periodic 5
username admin password
username radius-test password
aaa server radius dynamic-author

radius-server dead-criteria time 5 tries 3
radius-server vsa send accounting
radius-server vsa send authentication
any help !!!Thanks for your reply , I know what's MAB , if you read my explanation again , i mentioned that the user is authenticated in the guest portal which mean that I have web authentication , and it is working fine .. The only issue is that I can not use the vendor1 username as part of authorization condition and this is because the switch is not sending the radius attribute type 1 to the ISE , thus , on the ise authentication log the MAC address of the client machine is shown as a username not the actual username ( vendor1)
as I mentioned also , I have exactly the same setup with ise 1.2 and 3750 switch and I do not have this issue .I experience this with 2960x only .
