Cisco Switching/Routing :: Packet Loss With LACP 3560E

Mar 11, 2013

I have a cisco 3560E switch setup with LACP, when using LACP i receive alot of packet loss / output drops
 
When a ping from the server behind LACP:
--- google.com ping statistics ---
44 packets transmitted, 39 received, 11% packet loss, time 42990ms
 
what would cause this packet loss with lacp?
 
some output from the switch:
 
Port-channel12 is up, line protocol is up (connected)
Hardware is EtherChannel, address is d0d0.fd58.7390 (bia d0d0.fd58.7390)
Description: LACP-PORT

Cisco Switching/Routing :: 6500 Packet Loss On Blade WS-X6748-GE-TX

Oct 2, 2011

we have a 6509 with ios 12.2.33SXJ
 
we have 2 WS-X6516-GE-TX, WS-X6516A-GBIC, and a WS-X6748-GE-TX with a WS-F6700-CFC daughtercard
 
our sup is a WS-SUP720-3B
 
we are experiencing packet loss for everything connected in the WS-X6748-GE-TX blade, right now we dont have any production device in that blade due to the packet loss we are experiencing.
 
this switch was running hybrid  before it is now running native ios, however I can't recall if we didn't have that packet loss before. do i need to update a firmware of the card or daughtercard (if this is possible, can't say i've done it before).

Cisco Switching/Routing :: 2960S Packet Loss Is Minimal If A Switch Fails

Apr 11, 2012

I have a Cisco 2960S stack and I'd like to tune the timers so that packet loss is minimal if a switch fails.To simulate a failed switch I have reloaded it while running a continuous ping to a management address on the stack's SVI: [code] As I see the same results when a ping is directed through the single switch (switched), and through the firewall (routed), I'm inclined to think that this is due to the stack failover timers on the Catalyst 2960S.Is it possible to change the stack failover timers (i.e hold down, failover etc), to speed up the failover process?

Cisco Switching/Routing :: 2960-S With GLC-FE-100FX Fiber Modules - Packet Loss

Apr 19, 2013

I have two 2960-s switches with GLC-FE-100FX fibre modules in and I am seeing packet loss over the link that is connected to the modules. When the interface is shutdown and brought back up it always comes up in half duplex even thought it is set to full in the config. I've seen other posts where you have to use the command no duplex then full duplex to get it to come up int full duplex. This does appear to work when I do a show int it says its full duplex however I'm stil seeing 20 - 40% packet loss on the link which suggests to me there is still a speed/duplex issue. The device at the other end is a Cisco 7200 which is set to 100Full. If I plug a Cisco 2811 into the fibre link I get zero packet loss which suggests its a problem with the switch.
 
I have changed the modules and fibre cables which makes no difference. As I stated at the start I have two 2960's both are showing exactly the same issue. Details of the switch are below the SFP are cisco branded:

Switch Ports Model              SW Version            SW Image
------ ----- -----              ----------            ----------

Cisco Switching/Routing :: 6509 Monitoring Session Experiencing A Large Packet Loss

Aug 16, 2012

I have been searching the message boards and wasn't having much luck. I am running some monitoring sessions on my 6509 and on the VLAN I am monitoring, I am experiencing a really large packet loss.  If we hook up a laptop to the destination port and run wireshark we are seeing between 80% and 90% packet loss.  I dont see the packet loss on the show port command, but I do on the show int vlan command.
 
The config is as follows:
 
Session 2
---------
Type                   : Local Session
Source VLANs           :
RX Only            : 500

[Code].....

I was doing some reading on Egress vs Ingress and I am wondering if the Egress SPAN replication state could be causing the packet loss that we are seeing or does the ingress & learn command override that?

Cisco Switching/Routing :: 3560E - Can't Get Into ROMmon

Sep 2, 2010

I upgraded four 3560E, 12.2(44) to 12.2(55)SEThree 3560 works fine, the last one stops after 17-18 seconds with a solid green LED. I cant get into ROMmon, the switch doesn't boot up. its like "dead but still alive"
 
My TS:
1: Removed all SFPs.
2: Reset PSU and fan modules.
3: Replace PSU and fan modules.
4: Try to get into ROMmon.(pushing mode button and break seq.)
Startup LED:0-1 seconds:    SYST: Amber    RPS: Amber    STAT: Green    DUPLEX: Green    SPEED: Green
1-17 seconds    SYST: Blinking Green    RPS: OFF    STAT: OFF    DUPLEX: OFF    SPEED: OFF
18 s--> (only testet up to one hour)    SYST: Solid Green    RPS: OFF    STAT: OFF    DUPLEX: OFF    SPEED: OFF
 
A working 3560EStartup LED information. If I compare a working switch with the faulty switch I can see about 18 seconds into bootingSYST change very fast from green to amber and continues with booting,this doesnt happened on the faulty switch (solid green 18 seconds).   Pushing MODE button, doesn't get me in to ROMmon, this works for all the other switches.On a normal 3560 it takes around 40 seconds before I get in to ROMmon. With this faulty switch it stops after 18 seconds(solid green) and it doesnt respond.

Cisco Switching/Routing :: 3560E - HSRP Gateway Failover And Routing Table

Nov 12, 2012

We have two Cisco 3560E layer 3 switches at the core of our network. The switches are configured as an HSRP pair and the clients on our network point to the HSRP address as their default gateway. So if CORE-A dies, then CORE-B will pick up the address and the default route for the clients will continue to be available.We also need to specify a few static routes on the core switch to allow us to get to specific networks. Is there a way to do this so that the routes failover in the same way that the default gateway does?

Cisco Switching/Routing :: New Default Vlans On 3560e Switch

Nov 2, 2011

3945 is running c3900e-universalk9-mz.SPA.151-4.M2
3560e is running c3560e-universalk9-mz.150-1.SE
 
I've got brand new 3945's with onboard 16-port 3560e switches.  On the first power up I see that there are several new vlans added that appear to be default vlans..

vlan 2 name fst2
vlan 3 name fst3
vlan 4 name fst4
vlan 5 name fst5
vlan 6 name fst6
vlan 20 name VLAN0020
vlan 21 name VLAN0021
vlan 22 name VLAN0022
vlan 23 name VLAN0023
vlan 99 name VLAN0099
 
I deleted the vlan.dat and reloaded the switch but these vlans come back. What these vlans are intended for and is there a better way to get rid of them?  What does "fst" stand for?

Cisco Switching/Routing :: VG224 Quits After Upgrading IOS To 15 On 3560E Switch

May 15, 2013

I recently upgraded a remote site of mine to IOS 15-2.SE ipbasek9 on 3 3560E series switches. On switch number 2 I have 5 VG224's running (vg224-i6k9s- m) 12.4(22)T3. After the switches reloaded the VG224's dropped their connection. After doing all basic troubleshooting I reloaded the 12.2 (58)SE2 ipbasek9 image back on to the 3560E's and the VG224's reconnected immediately after reload and all phones registered.
 
Is the problem a licensing issue with the 15.x IOS on the 3560's or do I need to upgrade the VG224's to IOS 15.x as well for them to connect and operate via the 3560e switch running 15-2?

Cisco Switching/Routing :: 3560E-24TD And IGMP In Layer 2 Environment

Apr 13, 2011

I have 3560e which doesn't appear to be passing igmp traffic to the upstream router
 
PC1 ----------- ASA ------------ PC2--------- 3560e ----------- 3825 -------------------- WAN --------------------- Router ------------- Server
 
My ASA runs SMR, has an igmp forward interface outside command on the inside and has a trunk port to the 3560e (V lans 32 & 48).PC2 is a test pc on the 3560e on vlan32. 3825 is my ISPs router on vlan32.
 
- if i try to access the stream from PC2 it works. 
- if i try to access the stream from PC1, i see the igmp join leave my ASA onto the 3560E (i've captured on the 3560e's link to the ASA). 

I've also captured on the ASA and i can see the igmp packet leave the outside interface but the join doesn't reach the 3825 (i've captured on the 3560e port facing the router and there is no join being forwarded).the switch is running in layer 2, 12.2(35r)SE1.

i am implementing tcp as per rfc 793, i have one doubt, while sending first packet, if that packet lost means, tcp will wait for RTO and retransmit the first packet, and after got the ack for first packet, then only it will send second packet or without getting the ack for the first packet it will send second packet.

Cisco :: Packet Loss Only Across The VPN?

Apr 18, 2012

My workplace has a UC-540 attached to a cable modem, attached to the world wide web.

When we make VOIP outbound calls through the standard ISP, there is no auditory packet loss sympton; however, when we make calls to out sister branch through our VPN, we experience auditory packet loss symptoms.

I would think the VPN should only be affecting the encapsulation of the data. To my understanding the VPN packets and non-vpn packets all hit the router at the same time, and transport over the web in the same manner. Why would there be packet loss over only the VPN??

--Regarding QoS, if a standard layer 3 device receives a VOIP packet encapsulated in a VPN, do the QoS bits in the VOIP packet get acknowledged, or are they hidden by the VPN encapsulation?

Cisco Switching/Routing :: LACP Fast Updates On 3750s?

Sep 5, 2012

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?

Cisco Switching/Routing :: Configuring 4507R For LACP And Trunking?

Apr 3, 2008

We're trying to configure our Cisco 4507 (Supervisor Engine IV) to allow a new Dell server with a pair of Broadcom 5708 GigE NIC's to aggregate its NIC's to give us a 2gbps link to the switch.
 
So far we seem to have got the team and LACP up and enabled, but the adaptor that the Broadcom Admin Util creates for the team is only showing a 1gbps connection where I would have expected it to show as 2gbps.
 
The individual NICs show as connected at 1gbps. We're not Cisco experts so are struggling on how to get the 2 NICs to aggregate.
 
On the server side we've done nothing other than create a team using 802.3ad LINk Aggregation using LACP.
 
This is what I think the relevent output from "sho conf" is, more available if needed.

switchport trunk encapsulation dot1q
switchport mode trunk
channel-group 1 mode active

We also want to utilise Link Agrrigation for the servers that attach to the switch. Would this config be correct?
 
port-channel load-balance src-ip 
int range x
switchport mode access
switchport access vlan 1 (They are all on the default vlan)
spanning-tree portfast
channel-group x mode active
 
(Then I would configure the LACP config on the server) Is there anything I am missing?
