Need to clarify if ip sla icmp echo operation is supported in catalyst 3kx switches (ip services)? on the configuration guide, commands are available, but on the feature navigator, i can't find the feature, only ip sla video operation. i don't have a device to test on here.
View 2 RepliesIf the 3560 or 3750 "X" series support GRE.I am pretty certain the older 3750-E does not support GRE (both in hardware and software)Was hoping the new super duper X series do. If not, it could get expensive
View 5 Replies View RelatedI am experiencing inconsistent echo-replay from devices connected via VPC to Nexus 5500s while pinging from the Nexus exec prompt.
In some cases I receive normal response when pinging from one Nexus, but no response when pinging from the other switch. In other instance I receive normal response to one Nexus, and duplicate replays to the other. It looks like a VPC related bug. NXOS is 5.1.3.N2.1

I'm trying to work out if I need to order the "IP services" image for a couple of C3750-X. I need to run OSPF on these switches, but find the IOS image requirements on Cisco contradict.
At the top of the data sheet it says: • Open Shortest Path First (OSPF) in IP Base image
On the product info page it says: IP Base: Enterprise Access Layer 3 Switching, including OSPF (Open Shortest Path First) for routed access
But in lots of other places it says you need 'IP services' for OSPF.
As the IP services IOS is quite a bit more expensive I would like to avoid buying it. What image do I need to run OSPF?
Any info regarding the number of MAC Entries of Catalyst 3560X/3750X Platform? I can find that number in 3560, 3750 ds but not in 3560x ds.

View 2 Replies View RelatedI am in the process of installing a 3750x (IOS 12.2 (53r) SE2 IP Base) Cisco Catalyst switch in a new network of just 2 PC's (2 hosts, OS windows7 64Bits). I have enabled SVI interfaces with the both hosts installed in 2 different network segments. We then start connectivity test. The response time for the PING command between both hosts remain below 1 millisecond, whereas the response time between the hosts and their correspondent SVI interface is variable, and at all time is higher than 1 millisecond, sometimes it reaches 17 milliseconds. (Note that the switch CPU usage is only 8% at the time of testing) We have performed this same connectivity test changing the 3750x switches and in two different locations obtaining the same results.

I cannot seem to get the Allied Telesis unit to connect to the cisco switch.I have proved the fibre link by connecting 2 AT Media converters over the fibre.Do I have to enable something on the Catalyst switch or is the AT Media converter not compatible with the Catalyst switch?
Is there a way to configure a VACL capture on 3560-x, we need more than 2 SPAN sessions. Feature navigator indicates that this feature is supported but it seems like it's not implemented in the IOS yet.
View 1 Replies View RelatedI acquired a 3560X-24P-L Switch which I wanted to use at our datacenter. However, I need a switch that supports OSPF. It came with a Universal IOS but there was no "Router" command under conf t. I downloaded and applied the latest "IP Base" IOS, but still no Router OSPF. Based on the matrix here > [URL] I thought "IP Base" supported OSPF, but what exactly is "OSPF for routed access" ? Do I actually need an "IP Services" IOS? From my download options, I do not see an IP Services IOS for the 3560X-24P-L so I'm left to assume that the switch does not support L3 / OSPF. So my question is this particular switch supports L3 / OSPF and what is Universal IOS?
View 5 Replies View RelatedHave a very peculiar issue with IP SLA. Firstly, the architecture.
1) There are two sites - A & B. Both have their own internet connection.
2) Sites A & B are connected via MPLS.
3) Both sites have the below topology.
3750 CORE --> FIREWALL -->ROUTER ---> INTERNET
4) 3750 has a Default route pointing to firewall .
5) MPLS router is connected to 3750. A default information is originated via BGP to MPLS at each location. So that default route is learnt as a backup path from any location if it has to lose its local internet.
6) IP SLA has been configured at each location to track the default route using icmp-echo to hit a public IP (i.e 4.2.2.2 as an example).
Issue?ICMP probes from Site-A via its local internet fails abruptly. I can reach the public IP mentioned above from my firewall pretty fine, but not from my 3750. Whenever i remove the tracking from the static default route & push in the plain default route without tracking, it works fine. Again, if i add the tracking back, it will work fine for an hour or so & then fails back again. To my bad, Site-B had recently gone offline due to some natural calamity. So, there is no other path for internet.
My config looks pretty simple
track 10 ip sla 1 reachability

ip sla 1
icmp-echo 4.2.2.2 source-ip 10.1.254.1

ios in 3750-x core is 3750e-universalk9-mz.150-2.SE.bin. But, client to client communication is happening without any dealy and icmp is less than 1 ms always.

View 3 Replies View RelatedI have ASA 5510 with soft version 8.4(5) installed. There are two interfaces:
IP 1.1.1.1/24 - inside
IP 2.2.2.1/24 - outside
I have configured PAT, so network 1.1.1.0/24 gets NATted to 2.2.2.2 address. Everything works fine, except I can't reach 2.2.2.2 via ICMP from the internet.
X.X.X.X 2.2.2.2 Deny inbound icmp src OUTSIDE:X.X.X.X dst OUTSIDE:2.2.2.2 (type 8, code 0)
But I have configured an access list allowing ICMP from any to any: access-list outside_access_in extended permit icmp any any
Thus address 2.2.2.1, which is binded to outside interface itself, is perfectly reachable via ICMP.
I've got two questions:
1) Is there a way to fix it? It will be handy for diagnostic purposes.
2) is it possible to configure the secondary IP address on the interface on ASA? I've read, that there are some complications.
I'm having problem getting ICMP echo monitoring on outside interface to work. I've set: icmp permit host monitoring_station_adress outside but I still get:
%ASA-3-313001: Denied ICMP type=8, code=0 from monitoring_station_adress on interface outside. I'm trying to directly monitor ip on ASAs interface outside.
I have access-group tied to "in" direction on interface outside. Do I still have to put "permit icmp" rules despite the fact that icmp permit outside command is set?
How do I disable ICMP echo on ea4500 - I don't see anywhere either in Connect or directly on the router web interface that allows this.
View 1 Replies View RelatedIn order to meet our requirements we had to configure PAT for TCP 80 on 2 external IP addresses to one internal IP in DMZ. TCP port 80 is being translated for both external IP addresses and it works as expected. However, since we have migrated to ASA both external IP addresses don't respond to ICMP echo requests generating following error:
%ASA-3-106014: Deny inbound icmp src outside:<Source IP> dst outside:<Destination IP> (type 8, code 0)
Previously we have been using Cisco router to achieve the same objective and it worked well.I have noticed that when I add "same-security-traffic permit intra-interface" to a configuration the message mentioned above stops appearing in a logs.
As far as I can tell ASA sends packet back through outside interface, despite the fact that appliance advertises its mac address in response to arp request for the same external IP address.Is there any way to make ASA realise that it should respond to ICMP echo requests on external IP addresses that have forwarding setup?
I do realise that ICMP would work in 1-to-1 NAT scenario, but we can't apply 1-to-1 NAT for 2 external IP addresses to point to one internal IP address.

The switch is configured for auto. If the EKG machine is set to auto, it will work and not cause problems. The link on the interface will show up/up and there will be output packets increasing. However, there will be no inputs on the link and the port is unusable. Unfortunately, even when the device is removed, the port becomes unusable for any device.
