Cisco Switches :: Quoting SF302-08P For Client Having Offices Interconnected

Nov 8, 2011

i am looking at quoting the SF302-08P for a client which will have three small offices interconnected via single mode fiber. I am planning on connecting them to a 3560 switch. Each office will have no more than 3 - 7942 phones. I reviewed the notes on this switch and it seems it should support this phone type without any issues. Any support/reliability issues with this switch and the 7942s ?

Cisco :: RSTP Configuration - 14 Switches Interconnected In Ring?

Apr 2, 2013

I need to setup a layer 2 network consisting of 14 switches interconnected in a ring. Obviously, the design of 14 switches in a ring network is dumb, not here to debate that. Unfortunately, it HAS to be a ring. I've been researching the best way to configure RSTP for this. From everything I've read all I really need to do is configure Primary/Secondary root bridge in the center, and change the Maximum Age field to at least 16 seconds? From what I've read you want a minimum of 3 second buffer + 1 second for each hop due to message age being added by each switch hop?

Cisco Switching/Routing :: 6509-E Switches Interconnected On Layer 3 Port Channel

Oct 3, 2012

We are currently designing  Layer 3 to the edge EIGRP solution  for our customers. The network is a hybrid of collapsed  core (Core to access) as well as a three layer design (Core/Distro/Access) for connectivity to the Data Centre, Internet, Wireless Blocks etc.The  core of the network contains two 6509-E switches interconnected on a  Layer 3 Port channel (no VSS). Access Layer switches (3750-X series running Stackwiseplus protocol)  connect to the core switches over p2p routed links and Distribution layer switches (3750X stackwiseplus) provide connectivity to the  Data centre, Internet, wireless blocks etc.
 
The access and distribution switch stacks(Cisco 3750-X) are set up with two or three member switches with uplinks multihomed to the primary and secondary core switch with each uplink included in EIGRP. In each of the stacks, one of the switches controls the operation of the stack, which will be  the stack master.As the Cisco Stackwise architecture is not SSO-capable but NSF aware, all Layer 3 fuctions must be re-established during a master switch outage. To minimize control plane impact and improve Layer3 convergence, uplinks should be diverse and originate from the member switches instead of the Master switches in the respective stack. This is as per Cisco recommended design solution.The above solution can be setup if there are more than two switches in the stack. i.e. uplinks are configured on the backup member switch modules.
 
1.But what about stack with two switches..Which switch should be set up as the Master for a two member stack with uplinks to the core primary and secondary from each switch(Master and Backup)
 
2. For Layer 3 routing, does the routing takes precedene over switch failures? Say for eg. In a two member stack, the master switch with uplink to primary fails, does EIGRP provide a fast convergence to route traffic via backup secondary and does not wait for the control plane on the switch stack to converge? All the access to core links will be set up for ECMP.

Cisco Switches :: SF302-08 Configuration

Apr 6, 2012

How do I make the following work with Cisco 302-08G ? I have a 4-port Cisco wireless/wired router that allows for a guest account. I also have Cisco SF302-08 that I bought so I could use its port/vlan mirroring capability. How should I configure the network, given the aforementioned equipment,  so that I can get a single point sniff.
 
Assume I have two wireless clients, one using the "regular" wireless SSID, and the other using the "guest" SSID.  I can see 192.168.1.x (regular SSID) and 192.168.169.x (guest ssid)  on the internet side (one the same physical cat5 of the wireless router. So far so good. But, I would like to use 302-08 to actually allow the guest SSID/network comm cable)unicate with the regular SSID/network. For example, if I ping 192.168.169.x from 192.168.1.x, I would like to see a response. Can I make them communicate properly with the 302-08 ?? if so, what do I need to do ?? (I will also have wired clients tied into the 302-08..so its important that it be the central sniffer point).

Cisco Switches :: Two AP541Ns - Bandwidth Limited Through SF302-08P?

Aug 9, 2012

Just put in an SF302-08P switch with two AP541N's. Just a Comcast modem connects into the switch along with the two WAPs, nothing else. Speedtest through the cable modem with nothing plugged into it is 48Mbps. Then connecting a single laptop via the switch shows a speedtest of 33Mbps. Then with the two AP541N's plugged in and using the same laptop over WiFi, I'd consistently seen 10Mbps for downloading. But going right back to the cable modem directly showed me close to 50Mbps in a speed test.
 
Have factory defaults in all the Cisco devices, and poured over the settings and it looks like bandwidth limiting is disabled. Suspecting maybe it is for QoS and to optimize voice, but I see definite places in the devices where I could designate optimizing voice and those aren't enabled. Then started thinking with tweaking the wireless frequencies, but didn't want to do anything too unstable.

Cisco Switches :: SF302-08P Camera VLAN Configuration?

Mar 13, 2012

I am in the process of preping our network for the installation of an IP Camera based security system on it will be running within VLAN 600 in our network, and management would prefer that general users are not even aware it is there.
 
16 Cameras will all be running off two SF302-8P Switches that will be uplinked to our Cisco 2960 Access Switches. Due to port limitations I need to daisy chain the two SF302 Switches.
 
ACCESS-302-CA-01 - Ge1 uplinked to Port on ACCESS-03 (Cisco 2960) On this switch Fe1-8 Need to be in VLAN 600 to communicated with the camera server which will be plugged directly into Ge2 on Access 302-02.
 
ACCESS-302-CA-02 - Ge1 Uplinked to Ge2 on ACCESS-302-01
 
Ge2 - connected to the Network Video Recorder.
 
I've defined the VLAN's in the switch and have VLAN 600 as Untagged for FE1-8.
 
how do I configure Ge1 and Ge2 on each switch to pass the appropriate VLAN conntent to the devices connected?

Cisco Switches :: SF302 - Ssh Prevent Prompt For Password

Oct 3, 2012

I'm wondering if anyone knows to set up the switch so that when I'm connecting via SSH, the switch doesn't prompt for a username if I supply one in the initial connect request? For example, we usually connect by typing something like the following at a command prompt:
 
ssh johndoe@10.10.10.10
 
Then the switch would prompt for a password. I've tried this on the Cisco SF302 but it still prompts for a username, and then the password.

Cisco Switches :: 7902G - SF302-08MP Compatible With Pre-standard PoE Detection

Cisco Switching/Routing :: Nexus 5010 Interconnected With Two UpLinks

Dec 11, 2011

We are looking for some latency in our net and I am trying to check if our STP implementations is running correctly - we have a simple flat network here and no blocked ports here - just two nx 5010 which are interconnected with two uplinks.A remote site - mirrored setup - with 2 10G dark fiber connections - one for each nx5010 - is connection a DR site. I have split the two sites in two stp domains by enabling bpdu-filter on the vpc between the two sites.

I have been running wireshark on the local segment for some time and see the STP RST ROOT announcement every 2. seconds  - this is probably normal ? I was looking for some alternate root negotiation packets which would cause the mac tables to be flushed.

Cisco VPN :: 1841 / Dual Wan / VTI Between Two Offices?

May 16, 2012

We have two offices with two 1841 routers. Each office have two wan links (one ADSL with dialer, one SDSL) with fixed IP.The adsl link is the default route with failover.There is only one VTI working properly with the config below (the adsl one). If I remove the route "ip route 0.0.0.0 0.0.0.0 dialer 1 track 1" both VTI are working properly, however all traffic is going to SDSL witch is not the behaviour we would like to get.

get both VTI working with default route to ADSL link ?

I support a dental office that just went in on an x-ray machine with two other offices. So, there is a total of three seperate offices each with their own Internet connection and each on a different ip scheme. They all want to be able to see the Win XP computer connected to this x-ray computer. Ideally, they would each want to be able to run their dental software on this computer.

Cisco VPN :: 5505 Create VPN Tunnel Between Two Offices

May 27, 2011

I have two cisco ASA 5505 devices and two cisco switches plugged to ASAs in each office. I need to create a VPN tunnel between two offices.
 
-Network behind the ASA1 in office1 is 192.168.1.0/24 with DHCP server – 192.168.1.10
 
-Networks behind the ASA2 in office2 are 192.168.5.0/25; 192.168.5.128/26 and 192.168.5.192/26
 
 All computers in office2 need to get IPs from DHCP server 192.168.1.10. I have switch in office2 with 3 VLANS and I can assign computers from different subnets to different VLANs.How can I archive this goal? Should I assign 3 IPs for ASA2 inside interface (192.168.5.1, ...5.129, ...5.193) as a default gateways for each subnet? Should I put dhcp helper address 192.168.1.10 on the switch for each VLAN?

FVS338 / FVS318 / VPN Between Offices For VoIP?

Jan 19, 2012

I have an Avaya IP office setup on a 1.5 mb T1 PRI at location 1. My second location is going to run IP phones over 15mb/1mb DSL connection. All calls will generate from the IP office at location 1. I will have 6-8 IP phones at location 2.I assume i need a VPN setup between the two office for the IP phones to work. I've been looking for the best VPN solution and it appears for a budget the Netgear FVS318 or FVS338 is the way to go. If I go that route do I just need a FVS338 or FVS318 at both locations?

Best Connection Options To Share Files Across 2 Offices?

Feb 18, 2011

Have 2 office locales. Currently have a Site to Site VPN over the public domain with 1 T-1 line on each side (different carriers). The performance is _poor_. A 2MB Excel file takes over 1 minute to open at the remote location (takes less than 10 seconds at primary location).Have approximately 20 users at the remote location (about 200 miles away); entry level firewalls; and primarily only work with MS Office files.

1) What are the differences between "Private Ethernet", "MPLS VPN", "Point to Point T-1s", and just old fashion Site to Site VPN? and is there one in particular we should focus on given we only have 2 offices?

2) Do we simply just need to increase our pipes on both sides from T-1s to 2 T-1s or a 10/10 IDE line to make our S2S VPN acceptable?

3) Is all that's really needed for P2P T-1s is to have the same carrier at both locations (this is available)? Do we still need VPN or if it's all over the same carrier it is secure?

4) If we go with Private Ethernet or Point to Point T-1s, would we then need another pipe to just get to the internet?

Cisco Switching/Routing :: Connect SF302-08P To Catalyst 3750

May 7, 2012

I am trying to use a SF302-08P switch to connect a conference phone (Cisco 7937) to my infrastructure.  I connected the G2 port on the SF302 to a Gig copper port on the Catalyst.  I configured both ports as trunked ports and port e1 on the SF302 as an access port for the phone.  VLAN 1 is the default VLAN and VLAN 10 for voice.  However, the phone does not connect to the Call Manager.  I have changed the configurations on the G2 trunked port and the ethernet port (trunked ports, general ports, tagged and untagged).  I have also changed the configuration on the Ethernet port (general, access, trunk, set it on the default VLAN, in the voice VLAN, etc.)  The SF302 connects to the Catalyst, and PCs connect OK.

Cisco Wireless :: SF302-08P Switch / 8 WAP200 - Massive Disconnection?

Feb 19, 2012

For a customer of mine I've installed 8 WAP 200 access points with an SF302 switch. The Access point are powered with POE. All seems to function properly: the clients are simple Android device and the connection appears solid.. We've a good roaming between access points (not seamless of course but is ok) and no particalur problems, also because the network is used to drive very LOW data (no internet): the clients opens a tcp connection to the server and sends only a keep alive packets over this connection.. Then sometime the server send a very small amount of data (some byte) to activate the display of the device and show a question.. the clients reply with some other byte of data and so on.. During an event of 3/4 hour we can do this 12/14 times, so the network load is nearly 0....

Last night the system suddenly stopped working: ALL clients (300) lost connection from their access points at the same time! How this can happens? The only reason that I can imagine is a power loss on the switch...
