I have struck in my some network configuration. I have two sf300 switches and cisco 827 router. Actually sf300 does not support dhcp server. I took cisco 827 as dhcp server and i create 4 dhcp pools in it. How i can configure in sf300 to take dhcp service from cisco router 827. Isit possible to configure 827 with bvi interface, when i was try i got below error. how to configure bvi interface and i will link that bvi to vlan on sf300. error in 827 router, How i can connect two sf300 switch for redundancy ? I connected giga4 SW1 and giga4 SW2 and mode trunk isit good or any other way i need to connect it.?
I am looking for a how to configure a DHCP server for a Cisco SMB 300 series switch to obtain an automatic configuration. Currently i am using a Cisco 1800 router as my DHCP server and the DHCP pool serving the 300 series switch is configured as follows.
ip dhcp pool Cisco_SMB_300 network 192.168.0.0 255.255.255.0 default-router 192.168.0.1
[Code]......
Looking at pcaps, I don't even see a tftp request going the server after the switch obtains an IP via DHCP. The config file format is exactly as obtained from the download backup section (pretty sure its not the issue since i don't see a download attempt). Also, the SMB switch is running the latest firmware image (1.1.1.8)
Looking though the admin guide i did not see specifics on how the DHCP server was to be configure for the auto configuration feature to work.
I need to configure a Cisco 2960 switch as a DHCP server. The current IP address will be on a different seed than the DHCP addresses. i.e.
Switch IP = 10.1.2.3, GW = 10.1.2.1, Subnet = 255.255.255.0 DHCP addresses would be 192.168.1.1 - 200, GW=???? (10.1.2.3?) and subnet would be 255.255.255.0
The problem is that sf300 does not support complete dhcp, for that i put different internet modem.
I connected one internet modem in vlan 1 so users from that vlan can access internet and default gateway is nothing but Internet modem ip. user in the vlan are not communicate with other vlan because, other vlan users default gateway is Interface ip address. How i can give access to vlan 1 to access other vlan .
See the attached.
I have to used static route in all 3 devices or any one.
I saw a post in [URL] that was close to what I need to do. But this site seems a better place to ask a question. We need to install a second switch (SF300-24P) to an existing network with an SF300 48P and an ASA5500 for gateway/firewall etc. the network on the 48p switch is 192.168.1.xx. We want to use the new switch for ip cameras and 192.168.2.xx.
I will assume I need to set up a vlan on the 24 port switch for the 192.168.2.xx ip range, i will call this vlan20. I will guess that I need to pick a port from the 48p switch and create vlan20 on the 48p switch to access the 24p switch. I want users on the 192.168.1.xx network to be able to access cameras on the 192.168.2.xx network. Do I need to add a line in the asa config file for the new switch?
I have an issue with the sf-300 switch model, which i am depolying in lapsafe trolleys. The approach is to wake the laptops from the guest VLAN (20) with WOL have them authenticate with 802.1x and use DVA to put the ports in VLAN14 so updates can be pushed to them over night.
I have configured 802.1x, guest vlan and DVA which works initially, all host wake from WOL, the laptops successfully authenticate and are assigned to the VLAN (14). This remains stable for a time then the hosts fail reauthentication. I have also noticed that when a host is disconnected from a port and patched into another port the initial port remains in the authenticated state and the new port authenticates the client but the hostnames are missing on the 'authenticated hosts' page of the GUI, DVA fails. The ports display a port-failure message for a time then moves to failed reauthentication.
The only way I can get it to work again is to reboot the box. From the logs I can see the macs of laptops being rejected and I can also see attribute 26 being ignored. See log below. I am unsure as to why host are initially authenticated but reauthentication fails, is it not the same process?.
I have 11 of these switches and have configured 6 which all display the same behaviour. These switches are not CISCO I do not understand why they have badged them. The protocols/standards are implemented differently. If you incuded 'general ports' as an answer in a CISCO exam you would fail. There are also other issues I have noticed with these boxes, I am not impressed!.
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?
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 SF 300-24 24-Port 10/100 Managed Switch and I am trying to set some VLANs. The image below shows how I want it to be setup:Since the remote site goes through the Internet, making port 20 an 802.1Q trunk over the two VLANs will give WAN connectivity to VPN/E-mail.I've tried all sort of settings [ see attachments] but can't get it work.
i have a customer that will use this switch model.I was wondering if there is any recommendation from like an AS-BU for the most appropriate software version and what would be ?
I am going to purchase SF 300 24p POE Switch and if this Switch supports the configuration via console? As i have ESW-500 Series switches and it does not support console.
We are trying to config vlan 10 for data and vlan 20 for voice on the same port - port 1 of swtich SF300-24P to run both data and voice on different vlans.Do I have to add vlan 10 as an untagged vlan to port 1 and add vlan 20 as an tagged vlan to port 1?If I do not want to assign the native vlan 1 to port 1, how can I remove it ? The GUI page - assign VLAN to port does not allow to remove it.Aslo, what mode shall I set up on port 1? General, trunk or access ?
I am using a fiber optic connection. I want to connect it directly to ASA5510. A WLC2504 will be connected to ASA and one Aironet AP will be deployed at first. (At this moment I am not using any Windows server but in near future I will need to deploy Windows Server 2003 in my corporate network) My questions are:
Can I configure ASA as DHCP server for my LAN?
Can I configure WLC as DHCP server for my LAN?
If we can configure both then what is the best practice from above two options? (I am new to Cisco stuff and first time user)
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.
We've just started with the ASA 5505. We do run a DHCP server on the inside interface, so it is in the same VLAN 1 as all of the clients. However, we cannot get it to work.We can't use DHCP Relay, as the ASA 5505 only allows to relay to DHCP servers in a different subnet.Or do we have to move the DHCP server to a different subnet. If so, how would we configure that scenario?
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?
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?
I Have a problem I'm trying to configure automatically my switch over ther DHCP when I start the switch it request an IP from the DHCP from here everythings is fine but it does nothing more,indeed I put on my dhcp the option 66 and 67 which is an adress of my TFTP server and a file to download and the switch seems not to understand theses options , I tried my dhcp with a cisco airport and everythings works fine the File from the TFTP is automatically downloaded into the airport...There is an option to add or am I missing something in order to make it work with my switch ?
I am trying to configure two 3845 routers to act as dhcp server and dhcp relay. Clients are connected to the router that relays all dhcp requests to the vrf instance which is used to connect it to the router wich is running dhcp server.
Router1 ip vrf dhcp_dns rd 8:1 int gi0/0 ip vrf forwarding dhcp_dns ip address 192.168.200.5 255.255.255.248
[code]...
So far I can see dhcp requests coming from the R1 and dhcp server on R2 replies with the dhcp offer but PC is not getting any ip.
Is there a way to configure a DHCP server for my internal subnet of 192.168.20.1 which is on a 3550 layer 3 switch from my 5505 ASA Firewall.My subnet of 10.1.1.0/30 is connecting my 5505 to 3550. All I'm trying to do is run a DHCP server down to my hosts. The only options on ASA 5505 is
dhcpd address 192.168.20.1 - 192.168.20.254 outside or inside, which conflicts with my subnet of 10.1.1.0 used to connect my internal subnet of 192.168.20.1 for the whole network.
When I used my router it did not need the (inside, outside) keywords and just an ip helper-address command. How do I configure my my firewall DHCP server to propagate the 192.168.20.0 network through my 10.1.1.0 connection.
when we use switch as dhcp server and we want to configure a DHCP relay on other subnet that is not connected to this switch, what is the DHCP server ip address for configuration of DHCP relay? Should we use vlan1 ip?
DHCP Relay on a SGE2000 switch.I have configured two VLANs on the switch, VLAN2 (192.168.10.x/24) and VLAN3 (192.168.9.x/24). I have the switch in Layer 3 mode. I have configured the DHCP relay server of 192.168.10.4 and the DHCP Interfaces as VLAN3. All of the IP Static Routes were generated by the switch.
If I put a client computer on a port that is Untagged VLAN 3 and try to get a DHCP address from the server on an Untagged VLAN 2 port I never get a response back.I have done some packet captures and here is what I have found:
I see the DHCP broadcast on the client computerI see the DHCP Request on the DHCP server coming from the IP assiged to the switch on VLAN 3 (192.168.9.254)I see the DHCP server respond with a DHCP OfferThe DHCP offer never gets to the client computer I can't seem to get a DHCP address to any system not on the same VLAN as the DHCP server. Option 82 is disable and I did try enabling it, which made no difference.
I have sample lab dhcp-client ------- (vlan62) sg-300 switch (vlan62) ------ dhcp server
When I set on switch :
dhcp relay : enable option 82 : enable dhcp server address: ip of dhcp
When debug packets from client to server, there is no 82 option in dhcp discover packets. I mirror all traffic to mirror port with wireshark. I can see dhcp packets but without option 82.
How to configure cisco 3560 to force the client only can get ip by dhcp-relay server ?
The company i am working in has 5 vlans which have been set an lay-3 switch(3560), uses the dhcp-relay server .(in svi configuration: ip helper-address X.X.X.X) well , that works ok~
Now , I got my problem: I need to force the client only can get ip by dhcp-relay server, that means if anyone set static IP manunally , he can't really access to anywhere (to provent anyone set static IP with malignancy )
I know if a h3c router , how to set this configuration n svi configuration : dhcp relay security address-check enable ) the how to configure on a cisco 3560 ?
