Does ASR 1006 support ping with datagram size of 18024 on Channelized E1/T1 interface
Note our observations as below:
we have recently replaced 7513 router with ASR 1006 router’s.
There is absolutely no issues in the production traffic after migration.
The operations team have this unique practice of testing the link by issuing extended Ping commands with datagram size of 18000 bytes to test the link (see screenshots)
This command works on the Cisco 7513 series routers but we are not able to get ping reply in ASR.
The maximum datagram size for ICMP packet where we receive response on ASR router is 14000 bytes on the channelized E1/T1 card however ASR can send/receive ICMP packets of 18000 bytes on Gigabit Ethernet interfaces.
The Typical configuration on the Channelized E1 interface is as below:
ip address 172.a.b.x 255.255.255.252
no ip redirects
no ip unreachables
no ip proxy-arp
no clns route-cache
There are few questions:
Does ASR support 18024 datagram size on chanelized E1/T1 card?
Is this a limitation?
Do we have some documentation which can support this claim?
We have 3 identical switches configured by someone else and would like to claim some of the Gigabit ports(G1/G2/G3/G4) for use on servers. When we try to change the wiring and configuration, we run in to connectivity issues. Attached is a des...
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
