We have one SGE2000P switch that we are testing in Layer 3. We have a very simple configuration with some vlans that we want to route to our corporate network, but I want to test if there is actually traffic coming out from the up-link port first.
1- Created the vlans:
VLAN1: 10.10.1.12 /16 (native)
VLAN10: 172.16.10.1 /24
[Code].....
Currently, we have a plain network and we are planning to 'upgrade' it a little. We want to implement VLANs to separate wireless clients, workstations + servers and infrastructure devices form each other.As of now, we have no VLANs, and no managed Switches. We only have an RV016 that handles two ISPs and a 3rd party connection service to the office branches ( I belive they're using Frame Relay, but as far as we know, we are not concerned since we cannot touch their devices)
The reason behind the title, pointing towards the famous SGE2000P, is that my workplace is located in Argentina... and we don't have as many choices as some of you guys have ! In fact, I was unsuccessful trying to get a Cisco partner to contact me. We would like to replace the RV016 with a cisco 1941 (and a HWIC switch card).
So, back to business..! Assuming we will be using the SGE2000P switches, I was thinking about setting VLANs using 802.1Q through seven of these switches, along with a 1941 Cisco router. I'm expecting the 1941 to handle load balancing between both ISPs and the 3rd party link. Now, as for Inter VLAN routing, I would like to have gigabit traffic between VLANs.
Is it possible to use one SGE as Layer 3 mode to hande inter VLAN traffic (gigabit speeds) while using the 1941 as a end point device to reach internet (using PAT) ?Would you suggest me to use the 1941 for Inter VLAN routing, despite the 10/100 limitation(*) and use all SGE's in L2 mode? We need two ISPs, a third link for the FR connection, and finally the LAN interface. As far as I know, I'm limited to the gigabit builtin interfaces for WAN purposes, am I right?
I'm planning to separate voice and data traffic with two vlans. I have a COR switch catalyst 3750, a UC560 for VOIP with SIP trunk and SGE2000P as access switches. The thing is i had configured VLAN1 (data vlan) and VLAN8 (voice vlan), i've created the vlan 8 in the database on 3750 and let pass those vlans through a TRUNK port. In the SGE2000P configuration i've created the VLAN8 and the the ports as trunk for letting pass the two vlans for the PC and the IP phone. This works but some phones aren't registering, and for example i've unplugged a register phone and plug and doesn't registering anymore.

I am configuring it to pick IP address for phones from voice VLAN which is working fine but when I connect a PC on phone port it is also picking up an IP from Voice VLAN while default VLAN is data with different scope of IP.
I pack these switches and purchase ESW 500 series. I have ESW 500 at another client and they are working fine out of the box but this guy is giving me hard time.
I have a sge2000p to install with a uc520. I have all data traffic passing ok but voice will not work. Phones to not get ip etc.

So, how can I define an ACL to cover the RTP traffic so I can classify it?

View 1 Replies View RelatedI've got multiple SGE2000P & SGE2010P switches
Originally I was happy just set them all up in a stacked ring configuration. However I've become aware that my back bone fibre links are contantly pushed to their max.
So I've decided that I should change this configuration and unstack the switches and make them all stand-alone units. and I'll configure 2 cable LAG links between all my switches Theorically I should now get 2GIGs between each switch and to complete the ring in my network for redundancy I'll turn on Spanning tree.
However I've tested the speed and I just can not seem to get a LAG connection with 2 x 1gig cables to push more data than a single link 1gig link cable would.
My test enviroment(not using fibre optic cables just cat5e copper cabling):
4 x pc's(all gigabit network cards)
2 x sge2000p switches
PC1 ---(1G eth)--- /---(1G eth)--- PC2
[SGE2000P]===(LAG1 2x1G cables)===[SGE2000P]
PC3 ---(1G eth)---/ ---(1G eth)--- PC4
If I send files from PC1 & PC3 simultaneously to PC2 & PC4 They don't transfer faster than if I I just use a single 1GIG Link cable
looking at the LAG configuration it shows both cables are connected & the LAG looks like it's working. But it really doesn't seem to be running at the expected 2GIG?
The LAG fail over seems to work fine if I remove either of the 2 cables from the LAG the link continues to work. (sometimes it will drop a ping when removing or readding a LAG cable)
I have setup a new SFE2000 switch to work in Layer 3 mode using the IP address 192.168.100.254 on VLAN 1.I would like VLAN1, 2, 3 and 4 to be able to communicate with each other while VLAN2 (Guest) needs to be restricted from everything except web access and dhcp assignment from our server.I have been playing with various ACL's in an effort to accomplish this but so far I have drawn a blank in getting this working.

I'm wondering, though, is there a way to find out what data rate the stack interfaces are working at (since it's going over cable infrastructure we put in ourselves), and also what percentage of that bandwidth is being used?

When I have the customer plug in his fiber, there is a power light that comes on on the MFELX1 GBIC. Neither GBICs/switches show that a link or activity is occurring, but the presence of that light makes me think that they are connecting somehow. Are these two switches/GBICs compatible?

If I try and transfer files from either host the gig 0/1 trunk port on the 2960 leading tot he 3750 fa 0/1 port hits 100mb (using a real time bandwidth monitor tool), but why? This VLAN is on the same switch, why does it go one way up the trunk to the L3 3750 switch? The L3 3750 is the VTP server and the 2960 is a client. I would of thought the traffic stays local. The 2 hosts don't even have a gateway set.To sum up the typology the 2960 and 3750 are trunked using a single cable. The 3750 hangs of a ASA firewall using SVIs.Here is whatthe traffic looks like when copying a file between hosts (2gb file).

Have a quick question regarding inter-vlan routing on a 3750. Overview of network is ISP --> ASA --> 3750 (acting as my core and default gw). I have 5 vlan interfaces on my 3750, all w/ 192.192.x.x subnets, a 6th w/ 192.168.100.x, and a 7th w/ 192.168.200.x. I have enabled "ip routing" on the switch and can successfully ping from subnet A to subnet B as long as both devices are using the correct DG for their vlan, which is the switch. I have a few ports that are trunked as well that go to ESX hosts which break out the vlans according to the subnet the vm should be attached to. The ASA is set to nat internal traffic for all the vlans.
Now my question: short of applying an ACL to each vlan interface to block traffic from other 192.192.x.x subnets is there a better way to accomplish this? I want my 192.168.10.x subnet to be able to reach all the subnets, but don't want 192.192.10.x to be able to talk to 192.192.20.x for example. I was thinking to create an acl like this:
access-list 120 permit ip 192.192.10.0 0.0.0.255 access-list 120 deny ip 192.192.0.0 0.0.255.255 192.192.10.0 0.0.0.255access-list 120 permit ip any 192.168.100.0 0.0.0.255 192.192.10.0 0.0.0.255
and then applying this to the interface for the appropriate vlan.
I have problems in my Cisco network until I connected some Moxa devices.This Moxa are models EDS-316 and EDS-208
My principal trouble is the traffic UDP. Suddently the network don't permit the traffic UDP in VLAN where are connected Moxa devices.
During an hour the Moxa can send TCP traffic, but can't send UDP. If a Moxa device is unplugged from network, all devices connected to him can work offile from principal network, but if I plugg again the Moxa is like disable.
After one hour (more or less) the system restart all functions and work fine.I catch the logs from TXerrorsInPorts and all the ports where is connected a Moxa have errors all time.
I don't know which is the problem, but I think that problem is in negotiation from Moxa to Cisco.This is the configuration from a port where is connected a Moxa: [code]
Is it possible to configure LACP etherchannel to a Catalyst 3750? Playing around with the SMB switches for the first time.
I know how to do it on the 3750 but am having trouble figuring out the sge2000p.
I have a requirement to monitor all traffic going from the internal LAN to the cloud. The LAN is a layer 2 VLAN which spans multiple Cisco 4507 switched and other smaller switches.
The VLAN has an IP address which the hosts use as the default gateway.
The exit port is on a Cisco 3600X switch connecrted to 4507 #1 via a 10G fiber link. 4507 #1 connects the rest of the LAN. Those switches interconnect via 10G fiber and 1G copper links.
Currently the monitor host is connected to a 1G copper port, configured as a monitor port, on one of the backside 4507s The switch manager says he has the switches configured so that I can see all traffic on the VLAN.
We have a switch gc2960. It has ports configured on vlan 27 and vlan 29.It is connected to switch ch3550. It has presence of vlan 27 vlan 29 and also vlan 18 and several other vlans.Our internet firewall is connected to ch3550. It is a fortinet product, so this is not indicated on the diagram.
When the two switches were connected on vlan 29 access ports, pc's on vlan 29 on gc2960 worked as expected. vlan 27 clients of course did not work.When we switched the connecting ports to trunk ports, some weird stuff happened. Clients on gc2960 on vlan 29 could ping and resolve dns, but not browse the intenet. The same was true for clients on gc2960 vlan 27. We verified that packets from the web were coming in through the firewall. What we were thinking, is that they somehow were not being tagged to vlan 29 even though we were trunking.
When we set native vlan 29 on the trunk, then clients on gc2960 vlan 29 operated as expected. However, clients on gc2960 vlan 27 are still having this problem, we can ping and resolve dns but not browse.Consider the other switch ch2960-jstreet which has presence of vlan 18 and vlan 27. It is also connected on trunk to ch3550. We are not using native vlan on this trunk, and traffic works as expected.Is the lack of presence of vlan 18 a factor as to why gc2960 is not receiving the tagged packets correctly? Should the interface vlan18 on gc2960 have an ip address on the vlan 18 network?
I am trying to get a C2960-8tc-L linked to a sge2000p via the Gbic ports using GLC-SX_MM gbics but having no luck.Are these compatible and should I need to configure anything?

I configured Vlan 3750 and it work.Now I need to implement security : permit/block specific traffic between vlan [code] From vlan 72 I cannot have remote access on computer in vlan 34 and I cannot ping computer in vlan 34.
We run a network of several 2960G and 3650G switches in a network with a number of VLANs. One one particular VLAN (let's call it VLAN 10) it appears that non-broadcast traffic (i.e. normal unicast traffic) is being copied to every port in VLAN 10 only on one switch . The traffic is not crossing trunk ports and does not appear on other switches that have ports in VLAN 10. We first spotted this by noticing that a UPS port had an unusual amount of activity on our port througput graphs:
This traffic at 4 am is not expected and this profile is repeated across all ports in VLAN 10 on this switch (a WS-C2960S-48TD-L stack running IOS 15.0(1)SE3)\iffed one port using local SPAN (the UPS port) and discovered that this traffic was not broadcast, which was running at a normal low rate at all times. The traffic appeared to be unicast traffic from other ports of the sort you might see on a hub. It was from various hosts that live on VLAN 10, most (not all) of the conversations had one end station homed on the 'problem' switch. There are about 800 non-broadcast packets per hour and this is a busy VLAN so it does not account for all the traffic on the VLAN.
We have a pair of 6509 working in a VSS configuration (IOS 12.2(33)SX5). The 6509s connect to a pair of ASAs (7.2 code) running in an Active/Standby setup. These ASAs in turn connect to routers going to remote sites. I have configured Netflow on the following VLANS,
VLAN 10 - Servers Vlan
VLAN 9 - Transit/ASA VLAN (connects ASAs to 6509s). All traffic originating from any VLAN on the 6509 crosses this VLAN in order to reach remote sites and vice versa
I configured the netflow source VLAN 11 although I am not collecing any netflow from it.Although I have been getting lots of Netflow info, I noticed that netflow for traffic originating from any user VLAN on the 6509s going to any remote site via TRANSIT/ASA VLAN(9) does not get reported, I even tested with 4 GB traffic but no result. Only reverse traffic (i.e. from remote site to user VLAN) is reported as it traverses the Transit VLAN (9).
I read somewhere that egress netflow is not supported in 6500, but isnt traffic originating from a user vlan to a remote site via the transit VLAN (9) considered ingress with respect to the transit VLAN (9)? I would like to know whether bidirectional Netflow is supported on 6500 VLANS. I have mimimum control on routers beyond the ASAs, and since these ASAs run 7.2 code netflow is not supported, and Monitoring this Transit Vlan gives me extremely useful info.
I do get netflow biderectional traffic from the Server Vlan 10, but I think it is correlated by the netflow collector from vlans 9 and 10. [code]
I am trying to setup a network using Cisco 2960 switches with vlans configured. One vlan will handle video coming from four cameras that are connected to another 2960.
We have four cameras feeeding one port each on a 2960, that 2960 in turn feeds one port on the main 2960 which is the video vlan for that site. From the site it goes back to a Cisco 3750 to be sent over to a Sonicwall firewall. If we connect to the 2960 that the camera are connected to we can see the video, but not on the main site 2960.
I'm decommissioning my SonicWall PRO 3060 and upgrading to an ASA5550 (we're increasing our WAN link speed to 1Gig and need the 5550). In any case, I want to copy over the configuration from the PRO to the ASA. I have everything documented and I've started doing the changeover, but in looking at some other network diagrams on the net I'm seeing router symbols between the LAN switches and the ASA and I'm beginning to worry that I might need routers to do this which, of course, would increase cost quite a bit.
So my question is this: If I have a core switch carved into multiple VLANs and I connect each VLAN to a port on the ASA, will I be able to route and filter traffic from VLAN to VLAN through the ASA? If so how, in general, is this accomplished (I'm betting ACLs). I think that the ASA will be able to do this easily, but I just want to be sure before I get too far into the configuration of this unit,.
ASA

I have pair of 5596 switches in vPC. One host say "HOST A" is connected to the primary vPC peer and other "HOST B" on secondary vPC peer.Both are in same VLAN 10. Both hosts are vpc orphan ports as their NIC is configured in active/standby mode.I have configured span session on both vPC peers with span source as VLAN 10 in rx mode.Span destination is connected to secondary vPC peer. The issue here is that I am not able to capture the traffic originating from HOST A destined to HOST B which is traversing vPC peer-link.Same issue occurs for the traffic in reverse way and span destination on primary vPC peer. In a nutshell, any traffic which crosses vPC peer-link is not getting captured.
What could be the issue and is there any solution for it. Below mentioned is the span config and relevant interfaces. [code]
We recently extended our access layer using a pair of 5ks with extenders. We have a pair of 6509s at our core and they handle the intra-VLAN routing with SVIs. I recently noticed that access hosts connected to the extenders cannot pass traffic between each other if they are in different VLANs. The strange thing is these same hosts can ping devices in other VLANs as long as the other devices are not connected to the 5k environment.
For example, consider the following hosts. Each host has their gateway set to the appropriate SVI on our core.
HostA - VLAN100 - connected to 5k extender
HostB - VLAN200 - connected to 5k extender
HostC - VLAN100 - connected to 2960 off our core
HostD - VLAN200 - connected to 2960 off our core
Each host can ping each other with the exception of HostA and HostB. As for specifics, we use HSRP (no VSS) between our cores.
When I ping between hostA and hostB, I see the egress packets on either 5k1 or 5k2. I then see ingress AND egress on Core1. There are no ingress packets on 5k1 or 5k2.The egress packets from Core1 show the correct destination MAC address of the target host. The mac address table shows the mac address on po31.
