Cisco Switches :: Get InterVLan Routing To Work On DF300- 24 Port Switch

Jun 2, 2012

I am trying get inter vlan routing to work on a DF 300 - 24 port switch.  I have an existing company network on 192.168.111.0 and want to create a vlan on 192.168.1.1 that can talk to 192.168.111.0.  I have enabled layer 3 routing on the switch via console and also provided the ip routing command. I have the following VLAN's:
 
VLAN1 - Default 192.168.111.0
 VLAN2 - 192.168.1.0
 
I have enabled DNS and provided my two DNS servers 192.168.111.82 & 192.168.111.212.  I have set the VLAN1 interface to 192.168.111.217 and VLAN2 interface to 192.168.1.1.
 
Ports FE1 - FE15 are set to access ports and assigned to VLAN1 (untagged) 
Ports FE16 - FE24 are set to access ports and assigned to VLAN2 (untagged)
 
I have set a default route for the switch to 0.0.0.0 0.0.0.0 192.168.111.254 (Draytek 2600 router). I have connected a computer (A) to VLAN1 port FE3 and a computer (B) to VLAN2 port FE16.   I have set Computer A default gateway to 192.168.111.217 and its IP address to 192.168.111.94.    I have set Computer B default gateway to 192.168.1.1 and IP to 192.168.1.2.   
 
Computer A has access to Mdaemon, file server via network drives but no internet (cannot ping google) and can ping computer B and RDP onto computer B.
 
Computer B can ping computer A and RDP onto computer A but does not have access to the company network i.e MDaemon, file server etc.   It also cannot access the internet.
 
From the console I can ping [URL]and all ip addresses in the company network i.e. 192.168.111.82 (DNS server).  If I scan computer A wirh wireshark the internet starts working weird!
 
Configuration show below:

Cisco Switching/Routing :: Configuring Intervlan Routing Between 2801 And HP Switches?

Aug 5, 2012

I'm trying to configure intervlan routing between a cisco 2801 router and HP/Amer switches.  Using int fa0/1 and subinterfaces I was sure I had it configured correctly, but I cannot ping the default gateways when I place a host in a particular vlan.  Below is what I have configured.
 
HP switch - port 9 connects to fa0/1 on 2801
 ip default-gateway 10.1.100.1
trunk 9 Trk1 trunk

Cisco Switching/Routing :: InterVlan Routing With 3750 And 2960 Switches?

Nov 21, 2012

I am using a 3750 as a default gateway for multiple Vlans on a few 2960 switches. The trunk lines are configured and working and I have assigned ip addresses to each of the Vlan interfaces on the 3750. My issue is that I can only ping the ip address on the Vlan interface of the 3750 if I have a working computer plugged directly into the Vlan on the 3750. I only have 3 vlans on the 3750 that have hosts directly connected (vlans 2, 10 and 40) the other vlans ( 20 and 70) don't have any clients plugged into them on the 3750 but the hosts reside on 2 different 2960s that connect via trunk ports. How do I keep the vlan interface on the 3750 switch pingable when I don't have hosts directly connected in that vlan on the 3750? (yes, I have enabled ip routing on the 3750)

Cisco Switching/Routing :: About Intervlan Routing On Catalyst 3750 Switch

Apr 16, 2012

I have been looking into this for a while and I can't seem to figure out why my 2nd vlan is not able to connect properly to the net. My switch has 12 ports where my devices connects directly, they are all on Vlan 1 and they all work perfectly. on Port 12 I have a dlink router that is connected to a cable modem. the dlink router has an Ip address of 192.168.0.20,I created a second vlan (vlan2) and enabled dhcp relay on it. then I assigned port 9 on the switch to  (vlan2),my laptop which is connected to port 9 seems to get an ip address fine and able to ping only some devices on my network (vlan1) and is not able to,go out to the internet.

Cisco Switches :: SG300 / ASA 5505 Intervlan Routing?

Oct 17, 2012

I have an issue with correctly configuring sg300 layer 3 switch behind ASA 5505 (incl Security Plus License) The setup is as follows:
 
CISCO SG300 is configured as a Layer 3 Switch
 
Native VLAN 1: ip address 192.168.1.254, default route (inside interface ASA 192.168.1.1)
 
Extra VLANs on Switch defined
 
VLAN 100 with 192.168.100.0/24, default gateway 192.168.100.254
VLAN 110 with 192.168.110.0/24, default gateway 192.168.110.254
VLAN 120 with 172.16.0.0/16, default gateway 172.16.10.254
 
From the different VLANS(100,110,120)  I am able to connect to all devices in the other VLANS (except for Native VLAN 1; it's not pingable)From switch cli I can ping my firewall (192.168.1.1) and all other vlan gateways and vlan devices (VLAN1,100,110,120) From asa cli I can only ping my switch port (192.168.1.254), but no other devices in the other VLANs.
 
What do I need to change or setup in the switch or asa configuration in order for the other vlans to access the Internet through the ASA. I will not use the ASA as intervlan routing device, because the switch is doing htis for meI tried changing the asa int e0/1 into trunkport (uplink port on switch also), to allow all vlans, but as soon as I do that I cannot ping to 192.168.1.254 from ASA cli anymore.

Cisco Switches :: SG300 10 Layer3 And InterVLAN Routing

Apr 25, 2011

I'm trying to get the following running.
 
I have 4 Subnets
VLAN 1       172.20.0.0/16        with the default GW 172.20.200.254
VLAN 10     192.168.10.0/24     with the default GW 192.168.10.2
VLAN 59     192.168.59.0/24     with the default GW 192.168.59.254
VLAN 130   192.168.130.0/24   with the default GW 192.168.130.254
[Code]....
 
With absolutly the same settings I did this with an HP E4200-12G L3 Switch (which is now doing the job) so there is no routing mistake in the other components.For me it looks like, the SG300 doesn't like to be NOT the default gateway.

Cisco WAN :: InterVLan Routing Layer 3 Switch With C3560E

Apr 13, 2013

I 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

Cisco LAN :: C3750 InterVLAN Routing - No Internet Access For Client Switches

Oct 11, 2012

I have a test setup of a C3750 stack as a core and some 2960's as access switches.[URL] - The switches at the bottom is the new network (VLANNED). The switches on the left is the current production network (10.1.1.0/24) From the C3750 to the router is a /30 network.
 
There will be 6 VLANs but at the moment I have one configured. VLAN50 - 10.5.1.0/24 From the C3750 I can ping my current production network, internet, other VLANs in the testsetup, ... Everything.From the C2960 I can ping other VLAN's, reach the gateway, reach the router, reacht the currenct production network. But I can't reach internet. I've configured "ip default-gateway 10.5.1.254" on the C2960. C3750 relevant config is down below.How is it that I can reach other networks connected to the router and not internet from the access switches? I'm just trying to ping 8.8.8.8.

Cisco Switches :: SG300 Port Counters Via SNMP / Do They Work

May 24, 2013

I've got an SG300-10 connected back to back (trunked) with a Cisco 3560X switch, across a fibre link and am seeing some big inconsistencies in terms of unicast data transferred across the ports between them.
 
During a night time window of 4am - 6am I run backups which involves a large copy of files, that almost saturates a GigE link - we can see from the 3560X end that the link is running at a bit over 800MBit/sec of throughput, sustained.  The duration of this transfer is consistent with the size of the files being transferred (ie just over an hour, and is what I'd expect for a data transfer of about that amount).  Back-of-the-envelope calculations indicate that the 3560X is measuring this data throughput correctly.
 
However on the SG300 end of the link, which is also being polled by the same application (Cacti), I'm observing spikey counts of only around 20MBit/sec during that window.  These counters are very obviously incorrect - there's a huge amount more data moving across the port than that.  The incorrect calculations are showing on both the trunk port out of the SG300 (uplink) as well as the interface where the NAS is connected in (which is an access port).
 
Cacti is polling the OID:  .1.3.6.1.2.1.2.2.1.16.57  which translates to IF-MIB::ifOutOctets.57 = Counter32.I'm running version 1.3.0.62 but this problem is not new to this release - previous releases and 1.2 based releases also had this problem.
 
It looks like multicast traffic may be being counted correctly (that's only a suspicion though), however what I am certain of is that there is a very large discrepancy with the unicast traffic counts.Is this OID the correct one to be using for this switch?

Cisco Switches :: Can SG200-08 Switch Work With Dell PowerConnect 2716

Feb 23, 2012

I have no previous Cisco switch experience. I just received a brand new SG200-08 switch. It replaces a small blue Trendnet 5 port switch. I configured the SG200-08 with a static IP address which is on the same subnet as all our wired devices, then I installed it and connected a computer and printer and another switch to it. The other switch is a Dell PowerConnect 2716. I suddenly have no network connectivity with the router any longer. When I plug the network cable that runs from the PowerConnect 2716 into the SG200-08, the link status light will not go on for that port. I am going to be replacing the Dell PowerConnect with a Cisco switch as well, the SG300-10.

Cisco Switches :: ESW 520 24-Port Switch With POE Not Working?

Cisco Switching/Routing :: 3825 ISR - Traffic Route From Switch Port To Router Port

Jun 5, 2013

I'm fairly new to Cisco products am in the process of developing my network knowledge on a deeper level.  I have a 3825 with a HWIC-4ESW and I'm struggling to fully understand how the two "see" each other.  I've setup a V LAN with a layer 3 address on the HWIC and added the switch ports to it.  This seemed to allow devices connected to the switch ports to talk to the built-in router ports.  I thought this was all making sense until i applied an access-list to the router port.  It's a simple ACL i'm just using for testing and the only thing it does is blocks telnet from anywhere.  I know the ACL is setup properly because if I connect a device directly to the router port i cannot telnet to the port.  However, if i connect a device to one of the switch ports, i am able to telnet to the router port successfully. 

It seems that I'm missing something with how traffic flows from the switch port to the router ports and how the two "see" each other.

Cisco Switches :: Configure SRW248G4 Switch Through Console Port?

Jun 2, 2013

I want to configure my SRW248G4 switch thru console port. Unfortunately in this switch there is no RJ45 console port input, I can only see cosole port that is look like RS232 input. I bought two standard cisco console cables that have one end with db9 and one with RJ45.

Now I have and idea to put one end of one cable (db9) to switch, and one end (db9) of second cable in my computer (COM input/output)
 
I need to connect two RJ45 together - this is not a problem, I know how to do this. Here is the question :I know how pinout in my computer look like but i can't find pinout of console port in my SRW248G4. There is many pictures in Internet, for many Cisco devices but this isn't working. Maybe in LINKSYS pinout look different ?
