Cisco Switching/Routing :: Switch 2960S Did Not Configure Username
Jun 5, 2013
After i have already configured my cisco switch 2960 , i configured my console as the below [code] after i reboot my switch , i found that the switch asked me for username . However i did not configure username , how can i solve this problem , without password reset . I have already configured 15 switch , 100% this problem will be in all switches.
I have hybrid network in which I want to configure VLAN on Cisco 2960 S switch. I have unmanged switch where my DHCP server and other servers are connected. Now I created two VLANs on cisco 2960S and they don't talk each other, but as soon as I connect unmanaged switch to 2960S switch, both VLANs start communicating which I don't want. I want to listen server traffic from unmanaged switch from both VLANs but simultaneously I don't want to communication between two VLANs.
make a couple of SF300 switches to work properly with a C2960S-48TS-L that acts as core switch/basic router. I can't seem to figure out how to assign VLANs correctly in trunk and access mode on the SF300. The 2960S are a no brainer with IOS commands but the webgui in the SF300 is a pain.
I've configured the 2960S with 3 VLANs and I would like to have the SF300 switches connect to the C2960S-48TS-L through VLAN trunk and then configure the ports on the SF300 switches to belong to the assigned VLANs of my choosing. I would also like to have all the SF300 switches management interface in VLAN 50.
I am trying to configure etherchannel on 2 2960S connected by a flexstack with 2 ports g1/0/52 and g2/0/52 on each 2960.
these switch are connected to a CAT4500, I know that I can only use LACP because of cross-stack but when I force the switch to use LACP witch channel-group 2 Mode active the switch do this :
%With PAgP enabled, all ports in the Channel should belong to the same switchCommand rejected (Port-channel2, Gi1/0/52): Invalid etherchnl mode % Range command terminated because it failed on GigabitEthernet1/0/52
I don't know how to bundle the 2 ports on the 2960 stack. each time I use : channel-group 2 mode on there is no error
but the switch do this :
*Mar 1 00:45:32.290: %EC-5-CANNOT_BUNDLE2: Gi2/0/52 is not compatible with Po2 and will be suspended (trunk mode of Gi2/0/52 is dynamic, Po2 is trunk) *Mar 1 00:45:32.531: %EC-5-CANNOT_BUNDLE2: Gi2/0/52 is not compatible with Po2
I have a running setup having 2 Cisco 2960s 24 TS switch with Stack configuration. Now I want to add one more same Cisco switch. My questions are:-
1) How can I do this...(Should follow the same process as I did before.
2) Could I do this without impacting the service. i.e. without rebooting the switch.
3) What should be the connection archiecture as of now since there is two switch so it is connected 1 -1 and 2-2. but for 3 switch should we require to change the connectivity.
I use the Switch 2960S support PoE and 10 access points cisco.I have one more question:
-- If all 10 access points cisco use copper cable to connect to 2960S, 5 access points use power adapter and 5 access points use power from Switch. How Switch 2960S will provide power for 10 AP or switch 2960S will understand and only provide power for 5 APs?
In a new Cisco 3750, if the username and password is not configured seperately, what will be the default username & password. I have only configured enable password. when we access it remotely via telnet it prompts for username/password.
We have a Cat2960-S Series PoE+ currently running 12.2(55) SE5 ios with SW image C2960S-UNIVERSALK9-M.We want to upgrade the ios to the lastest version but found there are 2 version: 12.2(53) SE2 and 15.0(1) SE.Which is the best & suitable for upgrade?
I have enabled syslog on my Cisco 2960S swtich as shown below -
-logging facility local6 -logging host 10.11.12.122 transport tcp port 514
I have sent the port to TCP since that is what is configured on the SYSLOG server which is a CENTOS 5.8, running rsyslogd.I have tested the rsyslogd locally and it work.However i want to send any and all log messages in the buffer to my syslog server and it is not working.there is no firewall on the CENTOS and the ASA firewall filter is enabled for outgoing traffic.
I have a problem with extending the LAN on a client site . They are looking to extend the LAN with a 2960S-series switch. Already in place is a 4510 switch which the 2960 is connected to via fibre. The 2 switches are both set up but there is no connectivity as I cant ping between them or anything. The management VLAN on the 2960 shows line up, protocol down, which I believe means the VLAN is enabled but there is a form of physical mismtach on the ports. I have attached the configs of both switches. I feel it might be a problem with GBIC module compatibility. The SFP installed on both ends of the switch are GLC-SX-MMD. On the 4510, the SFP sits in a twingig converter (CVR-X2-SFP) but there is no light on it at all when the cables are plugged in.
I have a stack of 2960S (c2960s-universalk9-mz.122-55.SE2.bin) and the master has failed (used to have a priority of 14). The second switch has become master (priority 1) as can be seen below: [code]
If I connect a new blank 2960S (same IOS) through the stack ports, will the master sync its config to the new one without causing problems?As I understand the new blank switch will also have a priority of 1 and will by default be numbered as 1. So if the config is correctly synced and I later on want to make switch 1 the master, I need to set the priority: [code]
I have a live 28port Catalyst 2960S switch. By live I mean that there is an essential piece of equipment plugged into this switch that can suffer little to no downtime. Over the course of time the number of devices patched into this location has increased to exceed the 24 ports available and we have had to resort to adding unmanaged switches to fill the need. We have acquired an additional 2960 & stacking modules that I would like to stack together, keeping the existing switch as the master. It is my understanding that the stacking modules are hot-swappable and that this member switch can be added without bringing the master switch down, thus creating zero down time for the financial server that is connected.
The steps I believe that need to be followed are as such: write mem to existing switch and backup to our TFTP serverinstall the stack module in the existing (while powered up) and new (while powered down)place the 2 redundant FlexStack link cables on both switchesthen simply power the member switch on After boot the member switch will get it's OS and configuration from the master and I can begin moving CAT5 cables from the unmanaged switches to the stack.
I have a Cisco 2960S stack and I'd like to tune the timers so that packet loss is minimal if a switch fails.To simulate a failed switch I have reloaded it while running a continuous ping to a management address on the stack's SVI: [code] As I see the same results when a ping is directed through the single switch (switched), and through the firewall (routed), I'm inclined to think that this is due to the stack failover timers on the Catalyst 2960S.Is it possible to change the stack failover timers (i.e hold down, failover etc), to speed up the failover process?
I have a new Cisco 2960 S series switch with a basic configuration that needs to be uplinked or daisy chained to a Cisco 3750 switch. I am not getting any connectivity to the network with either a straight through or crossover cable. the port remains in amber but a 'show interface' indicates that the interface is up. I can manage the switch with a PC patched into any port on the switch with a static IP address. Must be something very simple that I am missing. Outlined below is the configuration.
i have an issue to connect a trunk between cisco switch and extreme switch i have many vlans that i want to cross via a link between cisco 3750 switch and a Extreme Alpine 3800 switch
I got one SF 300-48 layer 3 switch I tried to configure to use it in the office network.Unfortunately I'm unable to configure the VLAN settings.I need port one for input(VLAN2),port 7-15 for another vlan(vlan3) also need to connect with the vlan 4.port 15 is another vlan(vlan4) this is for wireless.Other ports are static.It doesn't get any connections with other vlans.I wish to know how to configure vlans in GUI mode.I tried , But I can't get the Vlan setting correctly.Also,I need to know how to communicate both vlans in GUI mode.
configure qos in Cisco 3750 switch.I have configured below template and applied on the vlan interface.But i am getting the hit on the access list but I am not able to get hit on the class map.
I am trying to configure a new 2960 POE switch, but seem to me the int fa0 is layer 3 interface. Is any way we can convert it to a switchport, so we can connect it to other switch in trunk mode?
Currently all the cisco phones are connected to this switch and configuration with only one vlan that is voice vlan .
1) what is the outcome of this configuration , i mean, what will be the expected output ? end of the day we need to prioritize the voice traffic but why other commands including threshold and buffers are mentioned with respectives queues , if I need to explain that what am i expecting out of this configuration ?
2) this is LAN QoS which i understood but again , do i need to configure policy-map along with class-map which is MQC on this switch ?
3) i have edge router where i have MQC already configured but confusion with this switch which is working as a Access switch .
4) I referred the cisco QoS document for the respetive model whereas we have policy-map configured on the same switch with class-map .
My understanding is if we have configured the LAN QoS , and mapped the CoS value with DSCP , we need not to have MQC.
We are using cisco ME 3400 E series switch. Which port we can use as CFM port ? We configured CFM in gig port.Is all the ports will act as CFM port or any separate CLI command is there for enable ?
I want to configure Cisco 3560 SWITCH with IP cameras. I need to configure the ports connected to Camers. IP addresses to the Cameras has been assigned.
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.
i configure the uplinks as etherchannel, i configure two svi interface on core switch int vlan 51(192.168.51.1) and int vlan 50(192.168.50.0) for this two svi int i configured two dhcp pool , when any of the pc is requesting for dhcp add i am getting dhcp request failed/
After configuring DHCP, all the users needs to get IP from USER VLAN and all the servers should get IP from SERVER VLAN. If yes, what are the steps as I am very new in this kind of configuration.
I have a Cisco 2940 switch and a Cisco 1841 router. I want to build two different VLAN networks on the switch, which do not have to communicate one with each other, but those VLANS should communicate with the router.
I read a lot of articles, i tried to configure properly the switch and the router but i still don't get them work.
I set on the switch, the GigabitEthernet 0/1 port to Trunk port and i had to set it a native VLAN. The problem is that only from that native VLAN, i can ping the router.
I haven't worked with infrastructure much lately but planning on replacing a Dell switch used for a small iSCSI SAN with a Cisco 3560x. Switch is sstorage ONLY, network handled through different switches. I believe I want to disable spanning tree and configure trunking for the 4 GB ports connected to the storage array. The switch is providing connectivity to SAN via multiple GB connections and then also multiple GB connections to 3 Vmware hosts.Can you look over the changes I made to config below and let me know if I am on the right track.
I also plan to add a second switch later with the 10GB modules to interconnect for redundancy (but not worried about that part for now). I do not plan on using jumbo frames.
Here are my questions
1) Is the best way to globally disable spanning tree for the switch?
2) Did I trunk the ports correctly below?
3) Should I apply any specific SmartRoles to the 4 SAN NICs (GE1-4) or to host NICs (GE13-20)?
4) Anything additional I should do to handle iSCSI data?
Here is a copy of the config so far with my changes marked in RED.
