Cisco Switches :: SG 300 Web Admin Interface Does Not Display Properly
Nov 11, 2011
Went to log into the web admin interface on my SG-300 today and I get this in both IE and Firefox:
I'm not able to login by typing user/password and just pressing enter. I've tried power-cycling the switch, however, since the power cycle, the font-panel system LED has been blinking green. I seem to recall, though I can't locate the reference now, that this means the switch is running with factory settings, but that cannot be right because:
1. I had previously saved a new configuration on the switch, which it should be using now.
2. It is answering on the configured non-factory IP address -- just not rendering the web admin interface successfully.
I've had this unit for approximately a month. This is not the first issue I have had with this unit (see: [URL] and I'm experiencing some strange LAN speed issues since I installed it. Do I need to RMA this thing?

We've recently shut down an interface on one of our ASA 5510s as we no longer use that service provider. The dashboard, however, still insists on showing traffic usage on this interface. How do I change the dashboard to display a more meaningful interface?

I have a ASA5540 firewall set-up with an interface MTU of 1500.
I suspect that we are receiving packets with a larger MTU but have not found an easy way of confirming this. Any command that can be run on the firewall to display the MTU packet size being received on an interface?
We are also running Solar Winds so could query an OID if such a variable exists.

I have a E4200 setup for 2.4 & 5G running the latest firmware. When I connect to the router wireless 192.168.1.1 and log in, it takes a few seconds for the web interface to display. Same happens when switching to the different config tabs. Is there any reason for this? I would think it would be immediate but it takes anywhere from 3-5 seconds for IE9 to respond.

Region : UnitedKingdom
Model : TD-W8970
Hardware Version : V1
Firmware Version : 0.6.0 0.11 v000c.0 Build 121203 Rel.46289n
ISP :
However, when I initially connect to the router, either on the LAN or remotely via the internet, the router takes a long time to display the initial page (up to 1 minute) and then usually displays the page without any variable data included. Frequently it also fails to show the menu on the left either. By hitting Refresh several times, eventually it will load the page fully.

IE cannot display website 192.168.0.1 so that I can set my password on my Dlink DIR-600 wireless router. I can however ping the website. Also, I can reach the website with my iPod Touch, yet I cannot set the password using my iPod since I cannot view the secure authentication code. I have reset the router to factory default. ipconfig command yields:Connection specific DNS suffix...domain.invalidIP Address...192.168.254.1Subnet Mask...255.255.255.0

Bought a new DIR-655 Rev B a few weeks ago.It's web admin interface has failed in some way. The device is still passing all user traffic in both directions, but attempts to connect to the admin interface with my web browser, from both the wired inside and the WAN outside fail. I can telnet to the actual tcp port number that it's configured for and establish a connection, but I can't get any response from it. At this point I'm expecting the only way I'm going to clear the condition is to power cycle the device when I get home from work. It is to note I have the device configured for https for the admin interface. Perhaps that's the more 'advanced' feature that's newer and is exhibiting some kind of bug, I wonder. I'm running the latest firmware available from D-Link.

Using a small network (WAN) with three 1921 routers (IOS 15.1(T)) connected via E1 links. One host (industrial PC - core 2 due running Win XP Pro) connected to each router. The spare Gigabit Ethernet port on each router is bridged with the active one (so a portable management PC (laptop) can be plugged in there and communicate with the router and the industriual PC.
Multicast routing strategy between the routers is as per "Anycast - Static RP", with PIM sparse-mode enabled on all interfaces and sink RP defined on all three routers.
Problem occurs when a (IPV4) multicast application on one PC communicates with the others:
(a) IGMP V2 membersip reports etc. work correctly at the sender and at the other two PCs receiving the multicast stream
(b) Multicast routing on the WAN is working correctly; running Wireshark on the receiving PCs shows that multicast data is received on the expected group.
(c) But, there is an error in the Ethernet packets
i. The first packet's Ethernet header contains the correct destination MAC address 01:00:5E:aa:bb:cc where aa:bb:cc match with the last three octets of the mulicast group's address, and that packet is received OK by the listening multicast application
ii. However, subsequent packets' Ethernet headers have the wrong MAC address 01:00:5E:00:00:00 (the last three octets are all zeroes and these packets are discarded by Windows on the receiving PC and not seen by the multicast application.
Problem is related to the presence of integrated routing & bridging; if I delete the bridge virtual interface,disable bridging and give the two Gigabit Ethernet ports their own IP addresses, the multicast reception works correctly; all received multicast packets have te expected value on the destination MAC address (matching the group address)I have used the same integrated routing/bridging configuration successfully on Cisco 2611 and 2811 routers and there was no such issue with the multicast packets.Have I overlooked some subtle aspect of configuration in the 1921 router or have I uncovered a bug...?
For reference - snippets from router configuration scripts
:
In the non-working configuration (with Integrated Routing & Bridging)
interface GigabitEthernet0/0
no ip address
duplex auto
speed auto
[code]....
In the working configuration all the bridging is gone and the two Gigabit Ethernet interfaces have a very plain & simple configuration in different subnets
interface GigabitEthernet0/0
ip address 192.168.212.1 255.255.255.128
no ip directed-broadcast
ip pim sparse-mode
duplex auto
[code]....

I finally managed to set up this DSL modem / router on Sunday to replace my old Billion router. I set it up with DHCP and running on IP 192.168.1.254.Last night, the power tripped, and when everything came up again the entire network was dead - PC's were not getting IP's from DHCP.I connected a known working cable directly from laptop to router and attempted to access 192.168.1.254, nothing.So I reset the router and try again to the default IP 192.168.1.1. Nothing. Tried another PC, nothing.Restart router, try again, nothing. Plugged into my other router and try again, nothing. When I initially got the router I had the same problem until one day it just worked, still no idea why

I took one and a half hours to get everything set up, I've got a PPoE connection, my problem is that ever since I entered the administration interface each and every page takes 2-5 minutes to load, it's absurdly slow, also, when trying to setup my WiFi, it timed out several times, I updated the router to the latest firmware, the same issue, it took me 4-5 retries to get WiFi set up properly. Sometimes navigating from page to page is quicker, 30-40seconds, but still those are some big times.
Is this normal behavior or do I have a hardware problem and I need to take it back and request a new one?
Mention: I am wired from a laptop, all the lights are blue, blinking nicely.

I was unable to access the web admin on my WRT160n v3 w/ latest firmware this morning. Reset config to defaults & was able to get in. Enabled HTTPS access & disabled HTTP access & was right back where I started; reset to defaults again & left both boxes checked. Can access via HTTP, but HTTPS requests get refused/reset.
The reason I needed access was that when I booted up my laptop this morning, my wireless card wasn't picking up an IP address via WIFI, only worked via ethernet, so I need to see what was going on there — several reboots of the router didn't fix, nor has it fixed the HTTPS access problem described above.

ive been having some issues with my internet, i had an attack on my pc recently by some american orginization, ive reinstalled new windows on my pc, reset my modem, and nothign seems to work, i have too many tunnel adapters in cmd ip config i think, bell canada hooked up my internet lines and they actually joined two or more wires together and strung them up on the neighbours fence and mine and even wrapped it around a tree branch, god knows why they would even do that, maybe they think when the tree grows it will cost me money to fix it and theyll earn from thier mistakes instead of learn from them... anyway this is my ipconfig test results as explained in previous post from someone.Windows IP Configuration[CODE]

Is this known bug that you cannot backup (export) full running or startup config from this switch? Will this be fixed in next firmware? (btw, still no new firmware with CDP support for this script altough sales literature mentions that it should have already been available...)Switch does let you backup configuration as text file (which looks similar to normal IOS config syntax), but it doesn't contain all settings so the file is pretty much useless to restoring the config to another switch.At least following settings are missing from the file:
- management interface config (including DNS settings)
- passwords
- remote syslog server config
- SNTP server config
- IGMP config
- LLDP config

We are planning 3 Internet Connections into our building. 1 will be for actual Internet traffic, 2nd for Voip phone system, and 3rd for internal network for Active Directory...etc. Oh the AD servers are controlled by another business so technically this line is still considered and outside line and is a T1. What I need to know is how best to make this all work so that our internet phones use the VOIP system, computers can log into the domain and access that network but use the Internet network for actual internet traffic? We were considering a series of managed switches and creating 3 VLAN's but I'm thinking we instead need a new router that all 3 networks connect to and dishes out DHCP to computers and phonesn example network is below.192.168.1.x ----> Internet (all computers use for internet traffic)72.10.10.x ----> VOIP (All physical and software phones use this network)10.10.10.x -----> Connection to external company that controls our network and has domain controllers, mainframe...etc.

I am having some issues with getting DHCP Relay to fuction properly over our SG300-20 Switch.Out current layout is as follows. Hanging off the SG300-20 are a pair of Clustered Checkpoint Gateways with VLAN'ed interfaces in Both of our 2 VLANs, a 3COM 4200G In VLAN1 which has the DHCP server (And all the other Servers) connected to it, and a Pair of HP Procurve 2520's Stacked in VLAN 2 to provide PoE for our Phones/connectivity for our PCs.The problem is I cannot get the DHCP Relay to fuction from VLAN 1 to VLAN 2. If I assign an address in VLAN 2 manually to a device connected to the Procurves, everything works fine. I am able to reach both VLAN 1 and VLAN 2, but DHCP aquisition fails even if the device is connected directly to a port assigned to VLAN 2 on the SG300. The SG300 is running at Layer 3 currently also.
Here is a copy of the running config:

At our office we use seven Cisco 300 Series Small Business Switches. One main switch in the server room and one in each room. They work great! But I’m having difficulties getting the Auto Voice VLAN to work correctly. In fact, it seems to works straight away on a PoE model, but not on the non-PoE models.
Switch (main server room):
Cisco SG 300-28 (PID:SRW2024-K9)-VSD
Switches (one in each room):
Cisco SG 300-10 (PID:SRW2008-K9)-VSDCisco SG 300-10 (PID:SRW2008-K9)-VSDCisco SG 300-10 (PID:SRW2008-K9)-VSDCisco SG 300-10 (PID:SRW2008-K9)-VSDCisco SG 300-10 (PID:SRW2008-K9)-VSDCisco SG 300-10P (PID:SRW2008P-K9)-VSD
All these switches use firmware v1.1.1.8. The switches in each room are connected to the central switch by Link Aggregation. The main switch is configured in Layer 3 mode and all the others in Layer 2 mode. We have a lot of VLAN’s configured. For this problem allow me to describe only the two that are relevant.
VLAN 102 - Internal Network (Clients)VLAN 104 - Internal Network (Voice) The switches on each room are mainly used for clients, printers and IP phones. The clients and printers should operate in VLAN 102. The IP phones should operate in VLAN 104. For this to work I have the 10 port switches configured as following.
GE1 – Trunk – 102U;104TGE2 – Trunk – 102U;104TGE3 – Trunk – 102U;104TGE4 – Trunk – 102U;104TGE5 – Trunk – 102U;104TGE6 – Trunk – 102U;104TGE7 – Trunk – 102U;104TGE8 – Trunk – 102U;104TGE9 – Trunk – 1P (LAG 1, with 1U;102T;104T)GE10 – Trunk – 1P (LAG 1, with 1U;102T;104T)
The network is fully routable. A DHCP Server is available. Each VLAN uses DHCP relaying. If we statically assign a VLAN to a port, that just works fine. Auto Voice VLAN is enabled with VLAN ID 104. All switches are configured the same. But this is what occurs…
When I connect an IP phone on the SG300-10P the IP phones are assigned to the Voice VLAN ID 104. If I would connect a desktop to that same port it is assigned to VLAN ID 102. Exactly as it should.But when I connect an IP phone on a SG300-10 the IP it is assigned to VLAN ID 102. But I also noticed that in some cases they are assigned to VLAN ID 1 and don’t get an IP Address. That depends in which order I change settings. The port its VLAN membership is then even changed to 1P. Although the port is recognized as an “IP Phone” by the smartport feature. I have noticed it does make difference if I modify the smartport macro and change the native_vlan paramater from "1" to "let's" say "102". That seems to affect it. Of course it may be just coincidence. What am I doing wrong? How should it work?How should you actually configure each port on a switch? (trunk?, Tagged/Untagged VLAN?)If you do not use Telephony OUI. Do you still need to configure the macros on the smartport defenitions?
I have tried about everything. I have also tried Telephony OUI, but it doesn't make any difference. I just can't get it to work properly on the non-PoE switch.

This is an odd one, possibly a broken unit but I have a SRW2024P which has been running for a couple of years all OK but some time ago I noticed I couldn't access the web interface. I decided to leave it until I actually needed to change something, which is now!
After much messing around modifying a null-modem cable to work (i.e. connected pins 2,3 and 5) I managed to connect to the console through HyperTerm. Did a full factory re-set and XMoDem'd the 1.2.9 software on again but still no luck.
I tried accessing the web console and telnet with the default IP and tried setting my own IP but can't even ping them.
There are a few other peculiarities: The units MAC address in the console is shown as 00-00-00-00-00-00The units hardware version is blank in the consoleBoth PING and TRACERT tests fail to any address except the units ownTFTP uploads fail to connect (the TFTP server doesn't even log an access attempt)All other clients connected to the switch are working fine and the port statuses in the console show working connections Basically; it is as if the web/config/admin 'module' is disconnected from the actual switch in some way?

I recently purchased an SG300-10 switch. Is it possible to change the TCP port numbers for the administrative services on this device? For example, if I wanted to change the web admin port from being availble on port 80 to port 8080, or move the SSH port from 22 to 2022, how would I do this?
I've looked over the web admin interface, and the Security > TCP/UDP services option looks like what I want, but I see no way to change a service's listening port. Is this possible?

How to properly power down the Nexus 5000 and the fabric interconnect switches? I have looked up and down cisco's and google web for steps, but they are all coming back with the answer to just disconnect the power cables after you have power down all the windows os and exs servers. Before i do that, I just wanted to make sure that that's the correct way to do it or if there are actual commands that I will need to run on the devices to properly power down. I know that the FI do have a command to reboot, but i need them to completely be power down.

Deployed two Cisco ISE 1.1.3. ISE will be used to authenticate wireless users, admin access to WLC and switches. Backend database is Microsoft AD running on Windows Server 2012. Existing Cisco ACS 4.2 still running and authenticating users. There are two Cisco WLCs version 7.2.111.3.Wireless users authenticates to AD through ACS 4.2 works. Admin access to WLC and switches to AD through ISE works. Wireless authentication using PEAP-MSCHAPv2 and admin access wtih PAP/ASCII.
Wireless users cannot authenticate to AD through ISE. The below is the error message "11051 RADIUS packet contains invalid state attribute" & "24444 Active Directory operation has failed because of an unspecified error in the ISE".Conducted a detailed test of AD from ISE. The test was successful and the output seems all right except for the below: [code]
Update:
1) Built another Cisco ISE 1.1.3 sever in another datacentre that uses the same domain but different domain controller. Thais domain controller is running Windows Server 2008. This works and authentication successful.
2) My colleague tested out in a lab environment of Cisco ISE 1.1.2 with Windows Server 2012. He got the same problem as described.

I tried connecting the router LAN port to the computer and 192.168.10.1 pulls up nothing.I tried connecting the modem to the WAN port and the LAN port of the router to the PC, but then I have no internet access at all. I tried resetting the router, still nothingAll lights on the router are green. I don't know what the heck is going on?

I get "Cannot apply because lack of HW resources." I am running firmware 3.0.0.18, and 3.0.1 release notes don't address that issue. TCAM utilization is at 3% Routing resources shows host: 200, routes:60, ip interfaces: 50 I have tried from the cli and get the same message.
