I can't connect to the console of switch cisco sge2010, I tried several console cables and none worked for me, I followed step by step manuals and nothing.
Also try the web 192.168.1.254 according to the manual but when I connect from the laptop to do ping to the switch doesnt work.
I am having some issues on my network and i think i have narrowed them down to a single switch.
On this switch the following logs can be seen
2147482407 05-May-2012 15:40:54 Informational %AAA-I-CONNECT: New http connection for user admin, source 10.0.5.135 destination 10.0.5.172 ACCEPTED

All other switches are OK and do not show anything in their logs. I am trying to figure out what could be going wrong. Spanning tree is enabled on all switches. The switch tihs is happening on, ends in the ip 172 and is where all building cables connect to. They also connect to 174. I have attached an image of the infrastructure so you can visually see what i mean.
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".
My requirement is that I want to set same console password in 12 switch instantly...
All the 12 switch are connected to a cisco 6500 L3 switch..
So how can i do that.. i have cisco acs 4.1...
can i do that by cisco acs 4.1 if not tell me an software or command ...
I have 2960 switch and i can't access it using my console cable .I can access other switches in my network ( 3560 & 2960 ) but i can't access only this switch.may be the console port in the switch damaged? or it's a bug ?? !!! although the switch is worked normally.

View 4 Replies View RelatedI have 2 Catalyst 2924 switch in a home lab. Both of them have developed the same problem at the same time (strange). I have tried all that I can think of. I can telnet to them but cannot access via the console port. On a telnet session I execueted a "write erase, reload" on one of them. As I anticipated this threw me out of the telnet session and I presently have no access to that switch.
The console cable is fine, works for all other devices.
I want to configure my switch via console cable, the switch boots up normally, and there are no configurations present on the switch. However, anything I type does not appear on the terminal client. I used several terminal clients (TeraTerm, PuTTY, HyperTerminal), all latest versions as well as different PCs. I even forced the switch to rommon mode, still, anything I type does not appear on the terminal client.
Here's the output of TeraTerm:
Boot Sector Filesystem (bs) installed, fsid: 2

After the last line, I can not type any command at all. I encountered this on three 2960 switches that we have here in our laboratory.
I've been assinged a task to connect our branch office with the head office, so that the IP Phones in the branch office can be connected to Cisco Call Manager at head office. To accomplish this they have given a Cisco 877 Adsl router a 10 Port 3-COM POE Switch and 3 Cisco 7911 IP Phones. Currently the there are 7 PC's Connected to 3 COM Switch which indeed is connected to a Internet router(Speedtouch). First I thought of connectiong the IP Phones to the Ethernet Port on Cisco 877 router but had to change my mind as the ports are non POE ports and I do not have adapters for IP phones. So I've decided to connect the Phones to 3 COM Switch and create VLAN's (DATA & VOICE) and pass the DATA traffic through Speed Touch and Voice traffic through the Cisco 877 router, but when I tried accessing the 3-COM Switch via Console I am getting Junk language( See the attachment for reference).
how can I pass through this Junk messeges and access the switch

i'm trying to enable command authorization for ssh as well as console access to a Nexus 7010 box (version 5.0). Following is the config:
aaa group server tacacs+ ACS5-1
server 10.12.19.11
server 10.12.19.12
source-interface loopback0
snmp-server enable traps aaa server-state-change
aaa authentication login default group ACS5-1 local
[code]....
As you can see, the default group configuration ACS5-1 for authenticatoin has applied to both defaults and console. But the command authorization does not appear to be applied to the console. As a result, when i login from the console and get authenticated, the command authorization does not trigger and i can run commands I'm not supposed to. In the configuration, I do not see "aaa authorization console" option unlike we have in IOS.
I planed to configure a new catalyst 2960 switch with console cable.
During the boot, all seems ok. but from my terminal client, I can't have access to configuration mode.Keyboard or Terminal client is not sending commands to the switch.
The terminal is blocked on this line Compiled Tue 28-Sep-10 13:44 by prod_rel_team.what can I do to get access to the switch? [code]
is it possible, to use a Catalyst Switch (in my case a 3560E) as a source for a console session to another Catalyst? In principle to use it as a console terminal server.

I was told I could just get any DB9- to- USB cable and that would work. I did buy a DB9-to-USB cable and it did not work. I looked up the installation guide for this module and it just said the console cable is DB9-to-USB but with no part number.

I was looking for a way to connect an AUX port from a 1700 router to a 6500 switch module console port, to see the output of the Switch's on the 1700 router, in case there is a network downtime, I could see what's going on in the switch, what cable should I use ? Also, is there is any kind of documentation for this type of config what have I seen is very few info.

View 2 Replies View RelatedI have a hybrid kind of network. I want to create create two VLANs on Cisco SGE2010 so that these two VLANs should not talk each other but at the same time they are able to talk Domain controllers, DHCP and other servers which are on other switches.I am able to create two separate VLANs but they stop talking with other servers(DC, DHCP, etc) which are on another switch.
View 7 Replies View RelatedI have 4 SGE2010P switches in L3 stacked mode in my production environment. I am having trouble routing traffice to/from my vlans. I have successfully set this up in a test environment and have compared switch settings, but still having trouble in the production environment.
Main network:
192.168.0.0/24, DG 192.168.0.1
Vlan 1 interface on switch: 192.168.0.253/24
Vlan 22 interface on switch: 192.168.22.1/24
Vlan 23 interface on switch: 192.168.23.1/24
I have assigned port 1/g14 to Vlan 23. I have enabled DHCP Relay and Option 82. I have set DHCP interface to Vlan 23. Static routes auto-genned as shown in image below. My DHCP server is on 192.168.0.16 on Vlan 1. It has a scope for 192.168.23.0/24 to give a DG of 192.168.23.1 (Vlan 23 IP address).I cannot get DHCP to give me an address from the .23 scope. So I tried to hard code an IP address into the client. When I did this, the switch sees the machine just fine, I can ping 192.168.0.253 (Vlan 1 IP address), but cannot ping any other IP on Vlan 1 (192.168.0.0/24)Do I need a static route somewhere that I am missing? I didn't need to on my test network, so I am a bit stumped.
I have a setup where - I have a cisco stack (4X SGE2010 Switches) trunking over to a 3COM switch. Both switches believe to be the "ROOT" of the network. Note The 3COM is running RSTP as opposed to the Cisco Stack which is running normal STP. To my understanding of STP - Essentially STP is not functioning! Both switches believe to be the "ROOT" so they don't shut ports down. (We are currently having major issues with ports going up and down for seconds at a time on both switches)
View 3 Replies View RelatedI realize this is just a small business switch, basically a rebranded Linksys, but why I'm only getting 200Mbits/s
- 48 port - 10/100/1000 , set to standalone mode
- 3 separate PCs on this switch , all are fast machines with Core 2 duo / plenty of RAM etc...
- all 3 auto-sense 1Gbps connection
I use iperf tool for bandwidth testing and no matter which PC I pick as server, which as client I get about 150 to 250Mbits/s
I am not looking for full 1000 here, but 200 seems rather sad....
- jumbo frames seem to make no difference
- I am using TCP test in iperf , standard no extra flags , 10 seconds, 20 seconds or even 30 seconds all come out the same.
- wiring is shady as some of it is just Cat5 , but when going from one laptop on the switch to another with brand new Cat6 cables I STILL only got 200.
Our environment consits of 4 cisco SGE2010 switches (stacked). I have implemented STP BPDUGUARD and Portfast on all client ports (suspected a loop). And our uplink to the Server DMZ recieves almost all of it's BPDU packets back(is that normal?) The issues lies where we have random ports dropping out - across all stacks for seconds at a time. We get errors/warning such as,Pinging between the DMZ network appears to be fine. Pinging from the client/switch network show packets being dropped quite frequently.All devices are on VLAN1 (I've have researched this and this could be the cause of the issue)
View 12 Replies View Related1 Cisco switch stack (SGE2010) in L3 mode, 2 Vlans.
Vlan 1 = 192.168.0.253/24, untagged on all ports except 14/15
Vlan 2 = 192.168.22.1/24, untagged on port 14 and 15
SGE2010 default route 0.0.0.0/0 next hop 192.168.0.1 (Checkpoint UTM)

DHCP server set to 192.168.0.16
DHCP interface set to Vlan2

Expanding the ICMP entry, it appears that the destination is the pc client since it shows a Dell mac address, and the source is the Checkpoint UTM (Sofaware).
I can ping and tracert from the Checkpoint to my static IP on Vlan 2. The same goes for the DHCP server to/from Vlan2, so I am confused as to why the routing is failing. I have tried adding Port Fast to the stack ports, but nothing changes.
what is the process of updating firmware on a SGE2010.
I would usually use TFTP - but, I can't see the TFTP command on these SGE2010's
I have currently a Dell powerconnect 6248 switch combined with a netgear UTM router. I have a basic understanding on how things should work but I don't have the knowledge to apply it as I'm new to setting up vlan and the person before me did the basic configuration like this:
defined 5 VLAN in the netgear router
defined the same 5 VLAN in the dell 6248
connected the dell switch to the netgear router via a trunk port.
Right now all the inter vlan traffic pass thru the netgear router as the dell switch as a trunk port connected to the netgear box who then give dhcp and set himself as the default inter vlan route. I would like to stop that since I would like the cisco switch to handle all the vlan routing for both switch and those switch to send their dhcp request to my win2k8 server.
I did set the sge2010 in layer 3 mode from the small business telnet interface. I then setup the same 5 vlan in the cisco switch.
If I understand this well I need to define an IP address for each vlan interface on the cisco switch for it to be able to route things, I have set them all as x.x.x.3 (x.x1.3 vlan 1, x.x.2.3 vlan2, etc) Then I need both swtich to forward all dhcp request to my dhcp box wich is in vlan 2. My DHCP server will have 5 range of IP address to hand out. my server are connected directly to the dell switch on vlan 2. I have set up a port in the dell switch in trunk mode and did the same thing in the cisco switch and connected them togheter to send all vlan packet. The current setup doesn't work so I need to finalize that setup so that everything works.
I have a 6513 with redundant sup 720-3B's that I cannot get onto. In short, one of the power supplies failed, it still passes traffic but I can't console or ssh to the box. Other than the two sup 720's, I have a 4 port 10gig card, a 16 port GBIC Card and an IDS module. I have tried removing the 10Gig, IDS and one of the sup's but still don't get anything on the console. I have rebooted the entire chassis and don't get anything on my console while booting. I have tried changing the speed of my terminal to every setting available incase someone has changed it at some stage but to no avail. I have tried swapping sup's, using only one at a time in the chassis but not getting anything. Is there anything else I can try to get onto this chassis? The power supply is a 3000w with a 32amp input. The failed power supply had tripped a switch, when i brought it back up, the power supply came out but the output failed LED is on. My #questions are, is there anything else I can do to try get onto the console, and is the power supply goosed when the RED LED is lit? I have reseated the power supply also but the same result.
