Cisco Switches :: Retrieving ARP Table From SF300 Switches Using SNMP?
May 22, 2012
I'm setting up an SNMP poller to retrieve the ARP table (ipNetToMediaPhysAddress) from my SF300 switches. I can retrieve the table from SF300-24P and SF300-48P switches running Firmware Version 1.0.0.27, but get garbage for the MAC address when retrieving that same table on the same model switches running Firmware Version 1.1.1.8. Is there an outstanding defect on this code level? How can I retrieve the table showing the IP address to MAC address mappings?
Im sitting with a few cisco sf-300 24 switches and i'm trying to get the Mac-addresses the switch have learned from each computer connected to the switch.
now we have 2 switches: SF300-24..on one SF300-24 we config it at layer 3 mode with VLAN configuration same as following [code] And we use port 26 on 2 switches SF300-24 is trunk mode then we connect both SF300-24 switches.But on SF300-24 layer 2 cann't inderstand VLAN from Sf300-24 layer 3..How to config VLAN on 2 switches SF300-24 Layer 3 and SF300-24 layer 2?
Any snmpset commands to add, modify and delete vlan table entries on SG300-10 switches? I checked url... however this information is apparently only valid for catalysts. The latest firmware is installed and the provided MIB files are used.
I have a new install with 3 SF300 switches, setup as vlan 2, the switch connected directly to the 2901 router has no problems, plug in a phone and it gets an IP, but if connected to either of the two swtiches behind the first switch, they do not get an IP. I am seeing the DHCP request hitting the router, and the router sending the IP to the phone, but it never gets the IP.
All ports are setup as trunk on vlan 2 including the ports that connect the switches together. Not sure what the problem is, but they are going live tomorrow and only have 48 out of 120 phones.
Trunk from 3500 going into SF300-8 #1 QNQTrunk from SF300-8 #1 going into trunk SF300-8 #2QNQ from SF300-08#2 going into Trunk SF300-24, All Vlans from Network 1 seem to be communicating properly between the 3550 and SF300-24 and is isolated from the Transport Network by QnQ. I am having one problem, I can not ping the SF300-24 or get to the management interface. I am able to access other devices on the SF300-24 Vlan1 from devices on the 3550 Vlan1 and vice versa.
An end user is looking to connect 21x IP Cameras to the switch and they require at least 6W port port. Now, the datasheet states that each port on the SF300 provides 15.4W.I need to double check so that the end user will not start connecting the IP Cameras and then half of them might not fire up.
cisco 2811 - DHCP server..If IP Phone 3905 installed in SF 300 he does not receive an ip address. [code] If IP Phone 3905 installed in the Catalyst 2960 - all OK.
My ISP is providing me with 1 public IP on a /30 network and 14 public IPs on a /28 network. In this example the 10.0.0.1 is the default gw provided by my ISP and 10.0.0.2 is my SF300-08. If I setup my router to route to 10.0.0.2 as the default gw through the interface between the switch and router, can I configure the static routes in the switch to route further to 10.0.0.1?
is it possible to have these 2 networks on different VLANs and configure inter-VLAN routing? I don't want the switch accessible from the 10.0.0.2 IP.
In my network I got 3 SF300 24 p switches. I managed vlan 10 for data and it is also a native vlan and vlan 20 for voice ,1st switch is the core switch and im having a problem in connecting them ?
my new Cisco SF300-48. I want to create 2 vlan (vlan 1 & vlan 2). The switch is set at layer 2. example : vlan 1 (port 1, 2, 3) , vlan 2 (port 4, 5, 6) vlan 1 can communicate each other (port 1, 2, 3) and vlan 2 can communicate each other (port 4, 5, 6)But vlan 1 cannot communicate with vlan 2.
We have a mitel 3300 PBX that is our DHCP server. It feeds an old Foundry Networks switch that nobody knows the password for anymore so I can't even look in it to get some clues. What I think I know is this.
Phones plug into the switch, PC's plug into the phone.
I am assuming this to be the case becase all the PC's get those numbers and when booting up a phone it comes up and says "vlan2 pri 5" during the DHCP discovery.
Like I said the Mitel 3300 is the DHCP server and our internet access is from the firewall's trusted port.
I have put the switch in L3 mode via the console. No matter what I try, the PC will always get IP addresses in vlan2's subnet. Even if I plug the PC directly into the switch.
I have factory reset this baby and all I have done at this point is put it back in L3 and changed the default ip address so I can get to the web GUI.
I am looking for some technical specs on the SF300 series which I can't seem to find in the 300 series data sheet: the maximum delay for traffic through the switchbuffer size for each switchportwhether or not the ports are suitable for shielded cable and connectors
After finishing all of my projects here at work, I decided to finally take a look at a sf300-08 that was left by my predecessor. I almost got into it once via browser but the UI crashed. So I downloaded the manual and proceeded to connect to the switch via rs-232. When I get to the log in screen I cant type anything in and when I try hypterterminal crashes.
I changed the setting from static to dynamic and the switch froze up. all lights on the panel flashed, when they stopped the system light on the left side continued to flash. I tryied unplugging unit as well as depressing the reset for longer than 30 seconds. Unit still the same.
I have a couple of SF300-24 switches. When I made needed configurations using CLI or GUI and then saved all configurations. The problem is that switches do not save configurations after reboot.
I have 4 SF300 switches I need to cascade together but the user guides do not seem to cover the physical aspects of cascading the switches.Here is what I was planning.
Does this sound about right?after initial use the setup will be changed to place switches 3 and 4 in a factory at which time we will then use the GBIC connectors and fibre to connect SW2 to SW3 and then SW4 back to SW1.
I have a SF300-24P switch running version 1.1.2.0 firmware. I want to get to the latest release (1.2.9.44) - can I upgrade directly to the latest code or do I need to step through all the versions in between?
I am using a Cisco SRP527W router for our small business. As this device only has 4 LAN ports I want to add another switch so as our business grows I can add more PCs and VoIP phones. I would like to use a Cisco SF300-24 switch and before I purchase am interested to know if anyone has used a SRP527W router with this range of Cisco switches. Are there any compatibility issues or will these two devices work well together?
We have just purchased 20x SF300-24P switches to be installed at our remote offices and we are unable to get RADIUS authentication to work. We already use RADIUS on all our primary network CISCO switches (e.g. 4506s¸ 3560s, 3750s, AP1231Gs,etc) and these work fine so we know the RADIUS server is working.
We are trying to use RADIUS authentication to gain management access onto these switches. Quite simply although we can see that the RADIUS server is accepting the username and password being sent, however the switch says “authentication failed” when to receives the response. We are using Microsoft NPS RADIUS Clients for authentication purposes.
We have upgrade the switches to the latest firmware 1.1.2.0, via the console it seems to have a very cut down IOS version so we cannot use the typical CISCO command set to configure the RADIUS as we normally would. Looking at the web GUI there seems to be a number of options missing including the Accounting port. When debugging is switch on there is no indication to say that any of the settings have been misconfigured.
The "Cisco Small Business 300 Series Managed Switches Administration Guide" and the data sheet indicate that this switch can do accounting requests with a Radius server. On the SF300 switch interface/CLI, there is only the authentication port, the accounting port can not be set (and nothing is sent by the switch to the default port). I suppose that the SF300-08 does not handle accounting. Maybe I have to change for another model.
i've a problem with my SF300-24 routing. That's my network configuration:
Port 1 to 12 assigned to VLAN 10 Port 13 to 23 assigned to VLAN 20 Port 24 has an ip 10.17.7.254 to connect with my deafult route, beacuse I've also a Linksys RV042 router, connected in turn with my ISP router, having an ip 10.17.7.1.
I was wondering if there was a difference between the Linksys SRW224G4 & Cisco SF300-24 switches. Going through the support docs I see the SF300 has limited L3 functionality in terms of being able to establish static routes between VLANS. Any further information would be of use.
Looking through the logs of our SF300 switches I am seeing errors for SNTP:
%SNTP-D-NTPBADVER: NTP server version not compatible
We have two NTP servers listed, both are MS Windows 2008 R2 domain controllers. The actual time on the switches seems to be correct but we are still receiving these errors?
I have a Cisco SF300-24P deployed at a customer prem running only a couple VLAN's - 1 customer related and 1 for management. Recently the customer inquired about changing his connection to Q-in-Q. I have changed the interface type to customer but then it selects vlan 4095 as the vlan associated to that port. How do I change that vlan or by default is that the only vlan I can use? Currently the customer is using vlan 904 and would like to continue to use that vlan in the Q-in-Q config.
