Cisco Switching/Routing :: Wake On LAN Setup With 3650s And 3750s
Jan 30, 2012
I've read the document (Document ID: 91672) on setting up WoL, but I had a few questions as this doesn't completely fit our situation.We have 4 3560 switches, 3 have only access to vlan 1, SW4 has access to vlan 1 and vlan 2, every switch is connected by fiber to a 3750.We want to enable every server/PC on vlan 2 to allow WoL packets to all PC's on the internal network (so WoL through all 5 switches). In the above document, it allows WoL to be executed only from a single IP/Server, is it possible to allow an entire vlan to execute WoL? or allow multiple IP's to execute WoL? Also, in the switch configuration it says to type
We do not use STP and is disabled, is portfast required for WoL use? if Port Fast is disabled by default, could this also be blocking a WoL packet from vlan2 to vlan1 on the same switch?
We've recently inherited a platform with little handover and also minimal networking experience.We're going 100 miles an hour in learning, but I'm a bit confused with the idea of a L2 switch with no IP assignments to ports, so using VLANs, and a L3 switch with IP assignments. And the combination of both.We have 2 Cisco 3750 switches, along with a whole host of other hardware, so we're starting at this "gateway" to start breaking things down.
If we have 3 stacked 3750s# running Layer 3. Do we need license for every switch? or is it one license for the 3 switches? Also is the license associated with the MAC address of a specific switch? What i# am trying to know also, is if we have to install one license and it is associated# with one MAC and this switch failed.. will the Layer 3 be broken?
I've got LACP-enabled port-channels between a Cisco 3750 stack and a few different switches (some Cisco 3750s and some Juniper EX2200s). The Ciscos are all sending slow LACP updates, the Junipers are sending fast LACP updates (but the Cisco they connect with is responding with slow LACP updates).
I have a couple of questions:
1) what are the pros and cons of slow vs fast updates? my research has led me to the conclusion that fast updates are better for network resiliency as long as you have plenty of bandwidth overhead (which I do at the moment). is there anything to add to this conclusion?
2) is there any way to configure the Cisco 3750s for fast updates?
I've to enable it on 3750 and nexus 7K switches. what are the steps involved? can we enable jumbo frame per port instead of enabling globally? i.e. we will only have few ports that will be using jumbo frames, rest of the ports will be using default 1500 MTU size.
Here's what I'm trying to do. We are having new storage servers installed that will be using NFS. I'm being told that they need to have their connections port channeled. Right now, the servers have connections to 2 different 3750s for HA. Is it possible to configure a port channel between these 2 connections?
can you stack a 3750 switch over fiber.....the answer is no, but the virtual switching supervisor 720-10G for the 6500 can create one virtual switch using two 6500s...
how can we get cisco to come up with a way for access switches to be stacked over fiber similar to above supervisor? i know of few of my site that would benefit from this...maybe they can come up with a vss appliance, similar to a media converter, to convert stackwise over fiber...then of course, you would need the same appliance on the other end....
I have a network with static routes witch I need to convert to OSPF.Never used OSPF, and do not have much experience in routing in general.The netvork is connected via some fiber links, but moastly wireless bridges.I have attached a drawing of how the network is.Routers are 3550, 3560 and 3750s.Each router is on a different physical site.
I am trying to setup the WOL for our enterprise. We have a C4500 setup with mutliple Vlans. We are using Microsoft SCCM server to wake up workstations for security update. The workstations are on vlan190 and the Microsoft server is on vlan 441
Here's my config
the config below
interface Vlan190ip directed-broadcast 100 (Enables the translation of a directed broadcast to physical broadcasts) access-list 100 remark ====== Wake-On-LAN ======no access-list 100 permit udp host 10.4.40.98 any eq 9 logaccess-list 100 remark ====== End of ACL 100 ======
how to configure the ASA 5500 with "Directed Broadcast" for Wake of lan from other networksegment. we want pass traffic from 192.168.10.0 network to 192.168.100.0 DMZ Network to turn on the server with Wake on Lan.
I read something about "Static NAT" but how do i make this one?
Recently I bought a Cisco RV180W and would like to setup an IPsec VPN server for my team. However, it's asking for the remote client's IP or FQDN. How would I know the client's IP if I'm using WiFi connection from different places? Also, I'll be using my iphone to connect and the IP is not static. Is it Cisco not going to support this feature or already working on a fix? I searched the internet and some of the old topic on this forum. Seems like it's an old problem for RV220W and I don't see any intension that Cisco is going to provide a fix.
Also, I have an NAS and a PC connected to the RV180W on LAN. Seem like it's not possible remotely turn them on using Wake On LAN.
Trying to configure my desktop to Wake on Lan. I have the BIOS set to WOL(PME) enabled, i have the ports set up, and everything. I installed a WoL Sniffer on the desktop, and sent a wake up command and the sniffer showed it came through (with the correct FF FF FF FF FF FF <Mac address repeating>). The router it's hooked up to has the UDP port 9 forwarding, ad that's what my WoL tool is sending, and i see the light by the ethernet port and it does indeed flash repeatedly when i try to send the WoL magic packet.However, nothing happens. It's shut down, plugged in, i used the soft shut down from windows,If it was the router, then the light wouldn't flash when sending it...
I have a Cisco SG 300-20 as the core switch, layer 3. It is 192.168.4.6 on VLAN1 and 192.168.5.1 for VLAN2 (VOIP). All the ports are set in trunk mode. DHCP relay is setup on this switch.
The phones connected into a layer 2, Catalyst 2960-S switch. All ports are set in trunk mode. Default gateway on it is set to 192.168.5.1.
DHCP for both VLANs is provided by a Windows Server 2008 R2 server (the relay IP 192.168.4.15).
There is also an ASA 5510 in the mix which is 192.168.4.1. It has a route added to it for the 192.168.5.0 network to go to the SG 300 (192.168.5.1).
Just the two switches can ping each other on the 192.168.5.x network when I "add vlan 2" to the trunk port that is connected between the SG 300 and the 2960. The phones don't get DHCP on the 2960 switch. And I cannot ping 192.168.5.x from the ASA or anything else on the 192.168.4.x network.
After a bit of reading on intra-vlan routing for the SG 300 switch, I am thinking the SG 300 has to be the "center" of things so I need to make it 192.168.4.1 to be the gateway for both VLANs and change the ASA to 192.168.4.2 for VLAN1, etc. And I really can't do asymmetric routing with this switch.
I have a power conncet 6224 with routing enabled with several VLANs setup.VLAN Database: 6,8,10,90-254VLAN 6 is our management vlan10 is for our core network services (DNS, Domain, Exchange etc)90-254 are isolated vlans.What I need to accomplish is to prevent vlans 90-254 from communicating with each other and only allow communication to VLAN 10 and the internet. All internet firewall work will be handled by our Sonicwall. [code]
I'm trying to set up per vlan routing on a 3560G switch but it's not performing as I would expect. I've got a server on the 109 vlan with a 10.1.9.100 address and a default gateway of 10.1.9.1 this address is an HSRP gateway and currently resides on 10.1.9.7. When I traceroute through to my user PC on the internal network it receives a response from 10.1.9.7 However, it is then denied by an ACL on the internal firewall which has been applied to interface Eth0/0. It should arrive at the firewall on Eth0/2.109 as it has the 10.1.9.4 address.
My goal here is to route traffic on the 101 vlan to a seperate interface on the internal firewall from 109 vlan traffic. I'm either doing something wrong or these routing commands aren't designed to work in the way I'm expecting (I couldn't find any documentation on the ip route command where it is followed by different gateways for different vlans)
I just inherited a network which has 7 switches (3750s) as a Stack. In there, there are 5 SVI (switch virtual interfaces) and in each of these VLANs, HSRP is configured.
Question:Is HSRP really needed in a Stack configuration?If so, what are the benefits?Can I simply clean-up the config and remove HSRP?
I have the rv042 vpn router which is the main gateway for our internet, connected to the vpn is one server for a software and then another computer is connected for a web server software, well i need to get these setup like so
Setup firewall rules that will block all inbound Internet access to the web server except port 443Setup firewall rules that will block all communication between the two internal networks, except ports 7000 and 1702These must be on two different internal networks
I'm new to using Cisco Config Professional Express but a lot of things are just "off" with this utility. But my problem for this post is specifically the 891W's internal access point, or initial access to it.
My situation is that I have some 891W's. It's my first time working with them, as well as with CCP Express (2.5). After isolating the router and my PC to their own network, using the IP my PC got via DHCP frmo the router I opened a web broswer and connected to the router. The initiial configuration wizard came up and I went through the various screens. One of those screens had basic config info for the internal wireless AP which I provided. Somewhere in that screen it asked for a Hostname for the AP, and a password. It doesn't askfor a username though. To ensure I wouldn't run into confision, I made sure to set every password I ever get asked to configure as the same thing so the AP's password was also the same.
However after I finish with the wizard, the java-based CCP Express begins prompting me for first the main router credentials which I provide and it gets the router config, then it prompts mefor the username/password for the Access Point. First of all, the initial config wizard had never asked me for the username for the access point, only the hostname, and the password. I had assumed it was just going to use the main router username, or perhaps a blank username.
In any case, nothing I type ever works. I've used cisco/cisco, or a blank username with my new password, or the same username as the main router with the password ---- nothing. This is now the 4th time I have completely Reset the router to factory defaults and while I am learning the use of CCP Express through repetition, I'd also like to get this thing configured and out the door so my customer can use it.
How to you setup ip routing on a Nexus 5500 I want to do vlan routing between an Nexus 5500 and Catalyst 3750. Nothing clever just have the 2 switches talk and vlans route between the two.
I am trying to configure the FE8 (WAN port) to connect to the Internet. We're swtiching ISP'ssoon so this router was set up at my office and has since been deployed at the client site. So far it is just plugged in and powered, with a console cable attached but no LAN cabling since this router will replace an existing one using the same addressing (except the WAN settings of course). So for now I am just focused on working on the WAN side since I have the ISP's cable modem attached . I had intiially used CP Express to config the wan port with an IP and mask and the various port forwarding options I intend to use. Now, connected via console cable, I tried pinging the IP of the wan port, which works. Beyond that, can't ping anyting (8.8.8.8 - a Google IP), also can't resovle any DNS names which makes sense with no apparent connectivity. Likely my config is just imcomplete. Nowhere in sh run do I see a Default Gateway, yet this ISP did specify one so I assume I need to enter it. Not sure what's the right way - I get confusing results on searches telling me either to use ip default-gateway or ip default-network. I want to think that it's as simple as entering in the IP but so far I've learned with the IOS that you never do anythign without knowing all the possible implications, which I don't. Also while I am at it, I don't know what I should have for DNS entries. This router will not be a DNS server for any internal systems that function will be managed by the two Windows 2008 R2 DNS machines. The ISP has also provided two IP's for their DNS servers. I thought it would be a simple matter of just adding two entrires via ip name-server command, which I did. So now I have four entries, first the two internal servers (inaccessible currently due to no LAN cabing to this router), and the two ISP servers. Can't ping those either, but again there's no default gateway.
I've been handed a requirement to try and get a multicast server working on my setup. Trouble is, I don't know if I can with the feature set I have on my switches. What is desired is that a multicast server (stand alone, but network connected, obviously) be accessible by everyone on the local network (multiple V LAN's, multiple SVI's) in the building.
All users will be connected to the one switch stack, although some will want to be wireless (which is one of the separate V LAN's) - I don't care if the wireless requirement goes by the wayside - they can sod off. :-) The main purpose will be multicast, high quality video.
I have a single switch stack consisting of two (soon to be 3) WS-C3750X-48P switches running the IP BASE feature set.
Question - can I do this on IP BASE, or do I need to upgrade to IP SERVICES?
If I can do it on IP BASE, does anyone have any links/pointers to setup this properly? Currently installed IOS is 12.2(58)SE2.
I have some 3750 switches in a network, where I need to transport a QinQ connection between them.
Switch A <-> Switch B <-> Switch C <-> Switch D.
Need the QinQ from switch A port 11 and to Switch D port 9. Between the switches interfaces are in standard 082.1Q trunk mode. What do I need to configure to make this happened? I need to make sure that the VLANs in and out of these interfaces do not conflict with the rest of the network, as some VLANs will overlap.
I have a 1941W that has a connection to my ISP (Gi0/1) and another connection to a remote lab (Gi0/0). Everything is working fine how it is setup. All my traffic from my internal networks can access the Internet and devices on the 192.168.201.0 /24 can access the Internet and the lab 10.89.0.0/16.
Now I want to have two devices (192.168.201.51 & .147) use Gi0/0 when accessing host 63.85.190.67. There is no route to this subnet since it reside in the remote lab. Here is what I have right now. How would I setup a PBR to have those two host use Gi0/0 when accessing 63.85.190.67
interface Vlan192 ip address 192.168.201.1 255.255.255.0 ip nat inside ip virtual-reassembly (code)
i was just asking if it is possible to create a L3 etherchannel between 2 single 3750 switches that act as our core, (running HSRP for the vlan and with a port-channel between the two) and a new switch stack of 3750s that will be routed to and managed by another party. Only i'd like to have the redundancy of 2 links connecting the new stack.If it is possible are there any best practices or preference in using PAgP or LACP or just going for ON.
We have multiple switches(Cisco 4510, 4507R, 3560's) within our network. I've been looking over the port settings between them and noticed that not all ports that are connected directly from switch to switch are trunked the same. Some are desirable on one switch and forced truck on the other switch.
I would like to setup RDP on my cisco router so I can access my server from outside my network. I also have a router from my ISP that has DHCP for my external IP address and DHCP for my internal as well.
I currently have IOS image cat4500e-entservices-mz.122-53.SG5.bin. According to my research it appears SPAN is supported on this OS. However, after looking at procedure notes using websites like here:
[url]... I cannot find and obviously not figure out how to use the SPAN command. My main objective is to simply setup a port mirror on one of my TenGigabitEthnet interfaces and from what I read SPAN is the best way to setup a tap interface on a cisco switch.
