Cisco Switching/Routing :: 3560 / Jumbo Frames And Connecting Non-jumbo Switches
Jun 11, 2012I currently have 4 3560 switches connected in a Mesh topology. These are all set to use Jumbo Frames and so are all the Servers that are connected to these.I now need to connect a 2950 switch to 2 of the 3560's which will have only desktop computers connected to it but i do not want to configure Jumbo Frames on this and any of the desktops.

Cisco WAN :: 6509 CPU 100% With Jumbo Frames
Jan 8, 2013I have two switches: Nexus 3064 (ver 5.0(3)U1(2)) and Cisco 6509.The 6509:
1 x WS-x6708-10GE 8 port Ten Gig module version 3.5, firmware 12.2(18r)S1.
2 x sup 720's, with PFC3A.
2 x WS-x6348-rj-45
4 x WS-x6748-ge-tx
The IOS is ipservicesk9-mz 12.2(33)SXH8b.Both switches have been running fine for quite a while(not connected to each other). I then ran a fiber connection between port Nexus:1/48 and 6509:Te9/1.When I ping (of any packet size) from the Nexus to the 6509 @172.19.4.254, the 6509's CPU goes to 100%. On occasion, we will get 1 out of 20 packets back in the reply.I reduced the MTU size on the three 6509 parameters until the CPU stopped going 100%.The magic number is 4175 bytes. 4176 and higher == 100% CPU.I am willing to put the fiber link to 1500, but how does one change that for just one port on the Nexus? I tried and it refuses to set the mtu. I also tried to setup a new service-policy but that didn't seem to work either.The Nexus users are all jumbo frame users. The users on the 6509 are all 1500 byte frame users, except for one user on a 1 gig port (ws-6748-ge-tx) line card. It is this user whom would like jumbos.
Cisco Switches :: SG 200-08 - Jumbo Frames Not Forwarded?
Aug 11, 2011What am I missing - can't get my new SG 200-08 Switch to handle Jumbo Frames
I have set the MTU size to 9216, saved the conf. and rebooted the box - however when I try to "ping -f -l 8000 xxx.xxx.xxx.xxx" through it (or to the switch itself) I recieve only "Request timed out"!?
I have tried MTU=9000 as well.....
F/W: 1.0.1.0
Is there anything, apart from increasing the MTU size, that needs to be done?
Cisco Switching/Routing :: Jumbo Frames On 3750s / Nexus 7K
Dec 8, 2012I'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.

Apr 16, 2013We have a requirement to send span traffic to a destination port for monitoring purposes on two 5000s with some 2000 fex boxes attached.
Some of the servers are making use of frames larger than 1500. we have not changed any mtu configuration on the 5000 since installation, and I can see the policy maps is still on 1500.
My first assumption would be that frames larger than 1500 will not be dropped, but it seemingly not (see below). is there a reason why the switch would forward jumbo frames? Also, is there a limitation on MTU for span traffic? There is a MTU command under the span session, but the maximum is 1518. From what I can read the frame will be truncated if it exceeds this. Does that mean the fragments will be dropped?

Cisco Switching/Routing :: 6509 Jumbo Frames Across Trunk And Sites
Oct 25, 2011I understand that jumbo frames need to be enabled end-to-end. I have two ESX hosts connected at each site. I want to enable jumbo frames for those ports, but what if not all host on the ESX are using jumbo frames, will I have drops and connection failures? So if i have two sites, each with a 6509 connected via a trunk and need to enable jumbo frames for a vlan between the sites how do I accomplish this?If I enable jumbo frames on the trunk link how does that impact other traffic between the sites?

May 23, 2012I have a Cisco Nexus 3064 that I am using as part of a flat network for the Lab. I have 30 Virtualization Servers(MS HyperV and VMware vSphere) connected to this switch and I want to enable jumbo frames. The Virtualization Servers are able to ping the local VM's using 8K bytes. However I am unable to ping from server to server using 8K bytes. I have configuration (in abbreviation). All the servers are in the same network which I configured as L2 ports with the "switchport" command. However, the interface "MTU" command is unavailable in L2 mode. I am only able to get the interface "MTU" command only in L3 mode with the "no switchport" command on the interface.
# int eth1/2-45
# no switchport
# mtu 9216
# no shut
I can ping the servers with less than 1500 bytes, but anything larger fails.

Cisco Switching/Routing :: Jumbo Frames Coming From Catalyst 3100?
Dec 2, 2012I have a Cisco Catalyst 3100 blade in a Dell server chassis that is trunked to a 6509.
When doing a protocol capture, I see large frames being sent from one of the servers in the chassis.
Example:
TCP:[Continuation to #1701] [Bad CheckSum]Flags=...AP..., SrcPort=HTTP(80), DstPort=2667, PayloadLen=2831, Seq=1489611217 - 1489614048, Ack=1719592331, Win=65535
I see lengths up to 6900+ bites coming from the server.
The switch has the global MTU set to 1500
system mtu routing 1500
and I can't seem to set this at the interface level. The server is configured to send 1500 length frames. Why am I seeing these jumbos? (the server is Windows 2003)
Cisco Switching/Routing :: Enabling Jumbo Frames On Existing 3560
Mar 1, 2011I have a pair of Catalyst 3560 GB switches that are trunked with two of the standard ports, and that have trunk ports connecting to a failover pair of PIX 515e's. We're considering adding a pair of cluster database nodes and an iSCSI SAN, both of which would need a dedicated interconnect VLAN that I'd like to employ Jumbo frames on. I don't necessarily need the VLANs to traverse the firewall trunks since they're private interconnects, but I need each host to traverse the switch trunks.
Since it seems I can only enable Jumbo frames on the entire switch (current standard frame size is 1500 and jumbo is also 1500), when I enable it what kind of possible negative impact could this have on my trunked ports as well as my host connections? I've read mixed reviews of users with iSCSI SAN devices seeing terrible performance when enabling jumbo frames so I'm apprehensive about enabling them on an existing network.
Cisco Switching/Routing :: Implementing Jumbo Frames On Nexus 5548
Apr 16, 2013The server team has asked me to implement jumbo frames on a single VLAN, the one they use for v motion. We have two pairs of 5548s, each pair running VPC for most connections. I am aware of many postings that describe how to enable jumbo frames globally, like this:
policy-map type network-qos jumbo
class type network-qos class-default
[code].....
I am not clear how I can extend this principle to one VLAN only.
Also, I am aware of a posting [URL], that shows some pitfalls of implementing jumbo frames in a VPC configuration. Pretty well all my connections are VPC, including all the FEXes, which are all dual-homed. In many cases, the VPC extends through to the servers so that the servers run port.channels across two FEXes. I am unclear whether the pitfalls are still valid, or whether I have to wait until my next maintenance slot (6 months away) to implement jumbo frames. Can jumbo frames be implement safely on the fly? How does enabling jumbo frames fit in with "conf sync" mode?
Cisco Routers :: RV180 Running Base Firmware (1.0.0.30) Don't Support Jumbo Frames
May 28, 2012I've enabled jumbo frames in Networking -> LAN (Local Network) -> Jumbo Frames on an RV180W running the base firmware (1.0.0.30).The switch seems to pass jumbo frames just fine (like ... almost every switch these days), but the router itself silently drops jumbo frames.ss this a known bug?This makes enabling jumbo frames on clients impossible, since it will break some external connectivity. (I.E. when two endpoints are on networks with jumbo frames, they will then negotiate a high MTU over the WAN, but the router will silently drop large frames and they won't get an ICMP Fragmentation Needed, etc. because the router simply drops large frames).
View 7 Replies View RelatedCisco Switching/Routing :: 9000 Jumbo Frames On Routed Ports Between Sites?
Oct 14, 2012We have a number of sites which have high-speed L2 links which terminate on our L3 switches at each site. The ports are between the sites are placed in routed mode.
I would like to use Jumbo frame between two of the network which will communicate across sites and 1500 mtu on the rest, is this something which is possible?
From my understanding is the mtu is set on the interface therefore if I set the mtu on the L2 link ports on both sites to 9000 then would this cause a problem for the 1500?

After recovery I see from the logs that all vlans and interface were suspended. I've attempted to look for reasons for a compatibility issue but I am unable to find what is checked and what could have been incompatible.

Cisco Firewall :: Support Of Jumbo Frames On ASA 5500 Firewall Appliance?
Feb 28, 2010Can any ASA 5500 in particular the ASA5510 firewall support jumbo frames (i.e. greater than the default standard 1500 Bytes frames)?. I plan to use the ASAs to setup a point-to-point IPSec tunnel and need an Application frame of 4Kbytes intact and not segment it.I have done little checking on the Cisco Website and see it mention of Jumbo frames on the 5580 on 10Gig interface but didn't see mention 5510. 5580s are way over-kill and expensive for what I need is to run a mission critical one IPSec point-to-point with maximum of no more than 100Kbps so 5510 is perfect for me but not sure if it can carry the jumbo frame?
On the routers and switches it's the MTU settings and they are configurable per interface and I am OK and the circuit is T1 which the Telcos said it's OK since it's physical layer so the only unkown is the firewall.

Disable the E3200 DHCP server2. Change E3200ip address from 192.168.1.1 to something else3. Disable the firewall4.Make wireless settings5. Connect it lan port to lan port with primaryrouter.The problem I am having is that after I finish step 2 the routerreboots with the browser trying to access it at the new ip address. But thebrowser will not connect.I am doing this on a laptop that is disconnected from my network while I am working on the E3200. It is connected byan ethernet cable to an E3200 lan port. I also tried it wireless with the same result. Browser will not connect at any ip address except 192.168.1.1 and then only after I factory reset the beast to regain the 192.168.1.1 ip address

Jul 6, 2011I have a 6 year old wrt54g that is working fine but old. I want to upgrade and will go with the 3200 or 4200. I really don't need the extra features on the 4200 since everything I have is hardwired (directly to two laptops and to two switches in other parts of the house for tv and printer). I want wireless for times when we move a laptop but it wouldn't be all the time, and we won't (for now) use the media options. The difference in price between the 3200 and 4200 is less than $25 so costs is NOT a factor in deciding.So should I just purchase the 4200 since price is not a factor or go with 3200; I want the most stable of the two and will never need the extra wireless features in the 4200.

Jan 11, 2012I used to have a Belkin router which was losing connectivity throughout the day for a few short moments. After looking at the logs it appears it was issueing a DHCP release randomy which explained the fault. Since it was old router I decided to replace it with a E3200. This worked fine for a few days but then I started to see similar symptions. So currently I am trying to figure out if it's the same issue as before. I tried looking for a log on the router to see if it was also losing/releasing the WAN IP, but apparently the router doesn't log it. I spoke to a tech rep on chat, but I don't think they understand what I was talking about (how frustrating). I even tried to explain it another way that if I hit the 'Release IP address' button and then hit the "Renew IP Adresss' button does this activity get logged.
Where can I find a log to see DHCP activity (on the WAN interface)? There is a DHCP log which shows all the LAN activity but this is not what I need for this issue. I find it hard to believe a mature vendor like Linksys doesn't log this activity?

I had checked information about HD on admin page, router understood that it is HD, but not provided share access to folder, also, there was no button, to setup it.I disconnected HD, tried to connect it using the Cisco Connect, it provided mistake with USB connection to HD and than with HTTP connection to router. I disconnected HD, tried to connect it manually: connect HD -> go to admin page -> refresh to show HD -> admin page freeze... -> reboot of router manually.
There was a lot of tries to connect HD, but all was failed.I connect HD to computer, it works successfully.I checked connection to router through USB, using my card reader and SD flash card, it works successfully.Information about HW:

I realized that my network had been set to 'work' for some reason, so I changed it to 'home'. As soon as I did, my printer spit out my test page. (probably 5 min after sending the doc.) I don't know if it was just coincidence or what, so I sent another page and nothing happened (yet).
Is this common to take that long? Is there a way to speed this up?
