Cisco Switching/Routing :: 3560 DHCP In Layer 3 Switch
May 25, 2012I have made a topology by using one 3560 switch and 2 2950 switches. I have also made 2 vlans name Clients and other Servers and vlan 1 is for anagement purposes. The left 2950 switch is for clients and the right is for servers. Clients is vlan 2 and servers is vlan3 . Now what i want is that my dhcp is should assign ips to clients in vlans 2 provided that servers are in vlan 3. I am also using a border router and i have introduced a default route on the 3560 to the border router.
Now when i assign static ips to my clients pc and server dhcp then i can ping between vlans but when i try to assign ip through dhcp then it wont work. Also the default route on the switch to the border router doesnt seem to work. I can ping only the border router when i put a default route on the border router instead of the 3560 switch.
Cisco Switching/Routing :: 3560 / Connectivity From Layer 3 Switch To Firewall?
Nov 29, 2012RACK 1 is the old rack and NEW RACK is the rack which is going to be procurred for some new Servers. All the Servers in the RACK 1 has a default gateway as PIX Inside IP. As of now the 3560 Switches acts as Layer 2 and does not have L3 IP routing enabled. How can I enable conenctivity between 192.168.36.0 range and 192.168.57.0 range wihtout making any change to current PIX inside IP address 192.168.57.1?Is it possible that I can enable IP routing on the 3560 Switches , create interface VLAN 36 and since already Switch 2 has it 's default gateway as 192.168.57.1 , Would the traffic from 192.168.36.0 be routed to 192.168.57.1 ? Or do I need to create static route for that ?Since L3 Routing is not enabled and since the 3560 Switches are just acting as L2 , the VLAN 2 - 192.168.57.0 range does not have any interface VLAN configured. When it is changed I would need to create interface VLAN 2 on 3560 Switches?

Jul 6, 2011I have the following scenario. Connected to a Cisco 3560 switch (fa0/9) is another Cisco switch (that is operating at layer 2). On the other side of that second switch is a firewall. I want to send traffic from my Cisco 3560 switch to a network behind the firewall. [code] However, when I try to add the ip address to int fa0/9, I get an error. Right now, the 3560 is operating at layer 2. I think that I need to issue the command: "ip routing" to put it in layer 3, then put the ip address on port fa0/9. However, I am concerned that I will mess up my production environment. Is there any other way of doing this? The "ip route 0.0.0.0 0.0.0.0" statement sends traffic out the gateway to the Internet. I just want to send packets to 209.52.62.16/28 out int fa0/9.

Mar 17, 2013I found that when I enabled layer 2 auto QoS in 3560 switch, I need to wait so much time to open a file in network drive. Howerver, when I disable the Qos. It can improve a lot. I have used a sniffer to capture the packet to see. Those default packet is in DSCP 0. Therefore, I think majority packet will drop to queue 4. How can I increase the buffer and threshold in order to improve queue 4 performance.

May 4, 2011I recently was asked to turn a routed link between our HQ and our DR Site into a trunked link to allow us to span our main Server VLAN up to the DR Site.I was informed by the ISP that owns the 100Mb Leased Line between the sites that the link was configured to pass dot1q traffic and I should just have to configure my links at either end as trunks to get the link to come up.
There is a Cisco 3560 at either end with Layer 3 routing enabled (obviously as this was a routed link previously).So, I scheduled an outage and configured either end as a trunk links as follows and repointed any routes from the /30 routed addresses to the management addresses of the switches on either side:
***For info VLAN 15 is the DR Site and VLAN 11 is the Server range at our HQ and was available on the connected switch***
interface FastEthernet0/24
switchport trunk encapsulation dot1q
switchport trunk native vlan 15
switchport trunk allowed vlan 11,15

Cisco WAN :: VLAN Routing On Layer 3 Catalyst 3560
Jan 15, 2013My first question is I have an access layer switch which is a single VLAN and I am trunking that VLAN to a distribution layer switch, I can ping the gateway on the distribution layer switch for THAT VLAN, But cannot ping the gateway address for the second VLAN I have on the distribution layer switch. I know it is simple, But I have forgotten and just need a push
Also I have a third VLAN set to route traffic not bound for those 2 VLANs out to a router is the statement "ip route 0.0.0.0 0.0.0.0 172.16.252.2" good enough and do I actually need to create a VLAN for that traffic? and if so, is an access switchport the best option?

Cisco Switching / Routing :: 3560 - Accessing Management Interface Using Layer 3 Link
Apr 9, 2012I am setting up a link between buildings that uses wireless links. I'm using Layer 3 routed ports on 2 3560 switches to handle the routing between sites. Normally I would just put these in a /30 and then the switches handle the rest. However, the wireless access points have a web interface for managing them that I want to be able to access, but it's only available on the single NIC that also carries traffic. What would be the best way of making this work? Should I make the link a /29 and give the access points an IP in the same range? If this is the case what do I use for the default gateway for the access points?
I have included a diagram to try to explain the issue clearer. The IP addresses in black are what I would do if this were a standard cable (and indeed this will work, but I wont be able to access the admin interface of the wireless AP) and the red ip addresses are the alternative if I use a /29 (but as I said, I'm not sure what to use for the default gateways).

View 7 Replies View RelatedCisco LAN :: 3560 Cannot Ping After Moving PC From Switch To Switch
Apr 15, 2013I have a 2 cisco switches that are at different sites one is a Cisco CAT4500 and other 3560. The connection between the switches is a layer 2 fibre link. CAT4500 and 3560 both have VLAN interface ip addresses in order for me to connect to the switches.
I have PC A connected to CAT4500 and PC B connecting to 3560. All these devices are the same VLAN and in the same subnet. I do have trunk links all the way though allowing this vlan as we run vlans. From PC A, I can ping CAT4500, 3560 and even PC B. This tells me everything is fine regarding Layer 2 & 3.
As soon as I move PC B and connect it to the other switch CAT4500 or move the other PC vice versa (this happens in both directions). Both switches learn that the mac address has moved locations and updates its mac address table accordingly. So when I do a show mac address table and show arp, everything has learned and moved fine. However when I try to ping any other device from PC B I cannot. So the 3560 switch PC B was originally connected to, I can no longer ping, the switch cannot see the pc also. It is as if PC B has not learned anything from the switch and cannot respond or reply to any icmp. I have tried this with different end devices, same thing. I am now thinking it has something to do with the switch.

Cisco WAN :: 3550 Port Forward Down Through Layer 3 Switch
Aug 18, 2011I'm looking at implementing a cisco 3550 Layer 3 switch and would like to know if i can forward ports down to all of my different Subnet Servers/Pc's.

Cisco WAN :: InterVLan Routing Layer 3 Switch With C3560E
Apr 13, 2013I am tryingto add a new VLAN on my C3560E Layer 3 switch for administration purpose.My goal is to make this VLAN for administration only and to let the administrators from 172.17.1.1 connect to any host of the internal network 172.16.0.0 plus exit to the internet via the default gateway 172.16.1.245.
Here an extract of what done so far:
ip routing
spanning-tree mode pvst
spanning-tree extend system-id
vlan internal allocation policy ascending
!
interface GigabitEthernet0/1
[Code]...
What happened is that:
1. The host connected to Vlan30 can correctly ping the interface it is connected to.
2, The internal network can access the internet
3. The host connected to VLAN30 cannot access the internet and cannot connect to any internal server.
Do I have to add a static route? This is a production envuironment and it is my first experiment with a layer3 switching in production, so I cannot mistake

The ASA5505 performs the following functions: routing to/from the WAN, firewall, NAT, and DHCP for each VLAN. It has an interface on each VLAN (10.10.x.2) for a DHCP server.
The L3 switch provides inter-VLAN routing and layer 2 switching. The L2 switch provides layer 2 switching, with VLAN support.
What should the default gateway on the L3 switch be? Should I set the IP of the physical interface connected the L3 switch to the ASA5505.
