Cisco Switching/Routing :: Nexus 5K To 2960 Switch - VPC Connectivity
Mar 30, 2013
Configuration details: I have 2 nexus 5K switches and both 5K is connected to four 2960 access switches in each floor through fiber(shown in the attached picture). I have configured each VPC for each floor and portchannel configuration on 2960s switch to communicate to 5K switches. Now I am not able to communicate PC 1 connected in 1st floor to PC2 connected in 4th Floor.
I have attached topology map of my infra and the configuration files also. 1st floor switch and 4th floor swich have same configuration except IP address and switch name.

We recently had a pair of Nexus 5k switches setup in our network. We had professional services handle the initial configuration but they weren't able to setup config sync for us. Each Fex is connected to each 5k, so we need a switch-profile to maintain a consistent setup on our interfaces. I went through the process in Configuring Switch-Profiles, but when I check the status of the peer, it says not reachable. [code]

I had a strange issue yesterday when onsite installing a new access switch.Port capacity full on a two switch stack of 3750 x48 PS switches (WS-C3750- 48PS-E)- New 2960 x48 PS - WS-C2960S-48FPS-L racked, with the plan of using it just as an edge switch via SFP Stacking cable.Setup the two connecting ports with simple initial config: - switchport mode trunk- no encapsulation option on the 2960, default dot1q- dot1q set on 3750 port- no shut on both sides.Connected the SFP Stacking cable but it didnt work:- %PHY-4-SFP_NOT_SUPPORTED: The SFP in Gi1/0/1 is not supported
This is ok as I had a backup:- Next step tried using 2 x Short Haul SFP SX GBIC's with LC - LC OFNP 50/125 fibre patch lead - no joy- Extra backup of 2 x Long Haul SFP LX GBIC's with the same fibre patch - no joy- Checked the fibre and it was not a cross over so transmit and receive going down the same side, switchedand still would not come up.- Used Fibre as a straight through and still the same.In all cases there was no indication of any life in the connection.It is pointing to a faulty fibre patch lead but I know it has worked in the past. Could it be something to do with the config or device incompatibility? Or any setting I need to activate?

From the multiplexer 9 ethernet connections are terminating in Cisco 2960G 24 port swith and it is connected through fiber uplink to one Cisco 3560G 48 port switch in first floor, which is connected to server.
How I will configure the 3560G to make communicate with 2960G and bring all these 9 ethernet connections to server. All the 9 connections are from different IP. and server also have different IP.

I would like to ask about following setup.
Internet --> Cisco ASA 5515X --> 2 Gbits etherchannel --> Cisco 2960T-48 --> 40 customers, each has own VLAN
Cust 1 -- VLAN 10 --port Fa0/1
Cust 2 -- VLAN 20 --port Fa0/2
Cust 3 -- VLAN 30 --port Fa0/3
Cust 4 -- VLAN 40 --port Fa0/4
Cust 5 -- VLAN 50 --port Fa0/5
etc
I have to provide sharing internet connectivity for all customers.Speed is 100 Mbits, I have to garantee 3 Mbit to every customer and max speed will be not limited.ASA do routing, firewalling, nat etc.

We have two 5548 switches connected to a pair of 6509 running in VSS mode. I am trying to understand the benefit of having bridge assurance on the uplink ports.
If we have the command spanning-tree port type network enabled we cannot do a non disruptive upgrade. If there is bridge assurance on the uplink it warns you of this. Yet if I do not run bridge assurance on the uplinks I can do a upgrade without any disruption.
Why in god would I enable bridge assurance on this VPC link if I cannot do a non disruptive upgrade?

We are in the plan of implementing a new 10gig network. For this we have chosen the Nexus 5596 and 2232 pair. What are the transceivers/accesories I should order for connecting 10Gig servers of NC552SFP dual port NICs to the 2232 in High availability (NIC 1 to 2232PP 1 and NIC 2 to 2232PP 2). Should I order the FEX SFP+ uplink conector to conect 5k and 2232 also (or its aded to the Nexus box itself) ? Also, is it fine to have Nexus 2232 in floor 2 and Parent neus in Floor 3 (say seperatd by a max of 400meters)?

In the existing network we have Cisco 2811 router connected to Corporate MPLS cloud. Cisco 2811 is connected to Catalyst 6509 switch(set based IOS with MSFC card). Along with that we have two Catalyst 5509. We are upgrading the access layer by replacing catalyst switches with Nexus 5548 & 2248.
For a purpose of testing I have connected 5548 & 2248. Created cPC and ether channels between two. SVI and HSRP configuredon 5548. I am terminating 2651 (test router) on 2248 port 101/1/1. On 5548 I have enabled EIGRP on vlans. I am unable to ping to 2651 from nexus switch 5548 and vice-versa. I can see both devices on CDP but I do not see eigrp neighborship formed.
What configuration should go in 2248 and 2651 in order to establish a connection between two? If test is successful then I will connect 2811 to 2248 during actual migration. I assume that in testing if it works for 2651 then it must work on 2811 router.

I have a Cisco SG 300-20 as the core switch, layer 3. It is 192.168.4.6 on VLAN1 and 192.168.5.1 for VLAN2 (VOIP). All the ports are set in trunk mode. DHCP relay is setup on this switch.
The phones connected into a layer 2, Catalyst 2960-S switch. All ports are set in trunk mode. Default gateway on it is set to 192.168.5.1.
DHCP for both VLANs is provided by a Windows Server 2008 R2 server (the relay IP 192.168.4.15).
There is also an ASA 5510 in the mix which is 192.168.4.1. It has a route added to it for the 192.168.5.0 network to go to the SG 300 (192.168.5.1).
Just the two switches can ping each other on the 192.168.5.x network when I "add vlan 2" to the trunk port that is connected between the SG 300 and the 2960. The phones don't get DHCP on the 2960 switch. And I cannot ping 192.168.5.x from the ASA or anything else on the 192.168.4.x network.
After a bit of reading on intra-vlan routing for the SG 300 switch, I am thinking the SG 300 has to be the "center" of things so I need to make it 192.168.4.1 to be the gateway for both VLANs and change the ASA to 192.168.4.2 for VLAN1, etc. And I really can't do asymmetric routing with this switch.

I have a statck of 4 2960s switches, with POE powered access points on 2 of them. All of the access points appear to be functioning normally. For some reason, on 3 interfaces connected to access points, I get the following when issuing show interfaces status:
Gi3/0/9 connected: T 7 a-full a-1000 10/100/1000BaseTX
^
My question is regarding the "T" in the status field. I can't find any documentation on this.

I can use Putty to SSH into my new switch (Directly connected to my laptop with ethernet cable), but I cant log into my switch.
Sent username "admin"
admin@192.168.251.1's password:
Access denied
It doesnt like my password, but I have only set 1 password (king) on this switch. I've configured 3 other switches with SSH and had no problem. Been trouble shooting for awhile and It'd be great if I could have a 2nd set of eyes take a peek, Also, my running config is attached.

I am setting up a new 2960-S switch and none of the recommended username and passwords combinations work. I have tried CIsco Cisco, <blank> cisco and various other permutations.
I have tried to reset the switch to factory defaults and it still doesn't work. The switch is currently connected to a 3560G and has been assigned an IP. If I try to access it from Network assistant it shows as unmanaged and I get prompted for a username and password.The switch is connected to another new 2960-S via a FlowStack module.

am using GNS3, and have the 16port switching module. I have created a PC instance and connecting to f/0/0 which is a layer 3 port, I can connect via layer 3 IPs. I then reconfigured and connected the PC instance via a layer 2 port f2/0 which is part of the 16port switch module. All 16 ports are by default in vlan 1. I assigned an IP of 10.1.9.1/24 to the VLAN and gave the PC 10.1.9.2/24. I cannot ping and I cannot even ping 10.1.9.1, the VLAN 1 IP. [code]

I can understand it 's one of those very basic questions , but how do I identify a Switch is Layer 2 or Layer 3 ?Looking through # show version command and checking the IOS version to be IP BASE or LAN BASE . Is it the right way ?Cisco 2960 is a Layer 2 or a Layer 3 Switch ? I noticed that access-lists could be configured which means that it 's a Layer 3 Switch , right?

I have a Cisco 1841 router connected to a Cisco 2960 switch.Users behind the router can't access the internet but when someone is directly connected to the switch with his PC and uses the IP Address found on the WAN port of the router, he's able to go on to the internet. [code]

Today in my rush to get home I plugged in a new 2960 stack and did a little bit of very basic configuration, but no passwords were set. I tried to telnet in and the message says that a password is required, but none is set. I tried the SDM as I hadn't turned it off yet and it is prompting me for a user/pass but I have no idea what to put in there. No console is available, it's a new office so no employees around either.

Document at url... is quite interesting,One of these goes about the behavior of a switch (2960-S and 3750G) when QoS is not enabled vs the one when QoS is simply enabled with "mls qos".What additional commands, beside "mls qos", would be needed so as to simulate as accurately as possible the switch's behavior when QoS is not enabled?

I have a client whom has asked me to enable web management on some of his 2960 switches. I did not think this was going to be an issue, and so I told the customer I would set this up for him.
Much to my dismay, I have been able to get http and https enabled, and then authenticating locally for the HTTP access. I then come to the screen once authenticated which is shown below:
The issue is that when I select "Web Console", it gives me a "Web Page Cannot be found".

I have a Cisco 2960-S Switch, It is connected to a jack in the building to check the settings, Interface VLAN 1 has an ip, there is a default gateway, Any host connected to switch can access the network resources. But the problem is that I have to use Serial Cable to configure it. I cant ping or telnet into it from any other device. PC's are on different subnets/VLANS.
Basically this switch is connected to a port in a different switch, Do i have to make a trunk?

I have a 2960 that bounced several times over the weekend and then appears to have lost its configuration. Using CDP from the backbone switch pulls up the information below. Is there any way for me to configure the downed switch from another switch on the network? I am trying to avoid having someone from the site try to find a console cable and a suitable computer with a serial port. [code]
