Hi All, Created subinterface using 3 commands 1. create sub-interfaces <interface name> 2. set interface state <interface name> 3. set interface l2 bridge <interface name>
Kindly help us know if we have limitation in configuring sub interfaces Please find our configurations We wanted to achieved 4094 vlans on 24 interfaces) 24 * 4094 = 98256 Vlan range in each interface First interface [1, 4094]. —> Working fine Second interface [1, 4094]. —> Working fine Third interface [1, 4094]. —> Working fine Fourth interface [1, 4094]. —> Working fine Five interface [1, 4094]. —> Working fine Six interface [1, 4094]. —> VPP Crash after 3050th Vlan Please find the crash log below. Kindly let us know want is the scale limitation for vlan creation gdb) bt #0 0x00007fb430ef4bfa in raise () from /lib/libc.so.6 #1 0x00007fb430ee0524 in abort () from /lib/libc.so.6 #2 0x0000558932cc94e4 in os_exit (code=code@entry=1) at /edpd_root/third-party/vpp/src/vpp/vnet/main.c:379 #3 0x00007fb4316901fc in unix_signal_handler (signum=<optimized out>, si=<optimized out>, uc=<optimized out>) at /edpd_root/third-party/vpp/src/vlib/unix/main.c:190 #4 <signal handler called> #5 0x00007fb430ef4bfa in raise () from /lib/libc.so.6 #6 0x00007fb430ee0524 in abort () from /lib/libc.so.6 #7 0x0000558932cc9493 in os_panic () at /edpd_root/third-party/vpp/src/vpp/vnet/main.c:355 #8 0x00007fb431568745 in clib_mem_alloc_aligned_at_offset (os_out_of_memory_on_failure=1, align_offset=8, align=64, size=565152) at /edpd_root/third-party/vpp/src/vppinfra/mem.h:143 #9 vec_resize_allocate_memory (v=v@entry=0x7fb3ed91f640, length_increment=1, data_bytes=376776, header_bytes=8, header_bytes@entry=0, data_align=data_align@entry=64) at /edpd_root/third-party/vpp/src/vppinfra/vec.c:85 #10 0x00007fb431630b82 in _vec_resize_inline (data_align=<optimized out>, header_bytes=<optimized out>, data_bytes=<optimized out>, length_increment=<optimized out>, v=<optimized out>) at /edpd_root/third-party/vpp/src/vppinfra/vec.h:149 #11 vlib_validate_combined_counter (cm=0x7fb3f232e578, index=index@entry=23547) at /edpd_root/third-party/vpp/src/vlib/counter.c:102 #12 0x00007fb431b6691b in vnet_create_sw_interface_no_callbacks (vnm=vnm@entry=0x7fb4321465e0 <vnet_main>, template=template@entry=0x7fb4301adc90) at /edpd_root/third-party/vpp/src/vnet/interface.c:574 #13 0x00007fb431b67d73 in vnet_create_sw_interface (vnm=vnm@entry=0x7fb4321465e0 <vnet_main>, template=template@entry=0x7fb4301adc90, sw_if_index=sw_if_index@entry=0x7fb4301adc74) at /edpd_root/third-party/vpp/src/vnet/interface.c:607 #14 0x00007fb431b77024 in create_sub_interfaces (vm=0x7fb4316abac0 <vlib_global_main>, input=<optimized out>, cmd=<optimized out>) at /edpd_root/third-party/vpp/src/vnet/interface_cli.c:770 #15 0x00007fb43162e97d in vlib_cli_dispatch_sub_commands (vm=vm@entry=0x7fb4316abac0 <vlib_global_main>, cm=cm@entry=0x7fb4316abcd8 <vlib_global_main+536>, input=input@entry=0x7fb4301adf60, parent_command_index=<optimized out>) at /edpd_root/third-party/vpp/src/vlib/cli.c:645 #16 0x00007fb43162ea68 in vlib_cli_dispatch_sub_commands (vm=vm@entry=0x7fb4316abac0 <vlib_global_main>, cm=cm@entry=0x7fb4316abcd8 <vlib_global_main+536>, input=input@entry=0x7fb4301adf60, parent_command_index=parent_command_index@entry=0) at /edpd_root/third-party/vpp/src/vlib/cli.c:606 #17 0x00007fb43162ee08 in vlib_cli_input (vm=0x7fb4316abac0 <vlib_global_main>, input=input@entry=0x7fb4301adf60, function=function@entry=0x7fb431686a70 <unix_vlib_cli_output>, function_arg=function_arg@entry=2) at /edpd_root/third-party/vpp/src/vlib/cli.c:746 Kindly help us with your valuable inputs Regards, M.
